(arenax): (arenax_ee.c:98) too many chunksThis error occurs when the primary index has been misconfigured partition-tree-sprigs for an all-flash namespace. To size all-flash installations adequately, you must account for the number of partition-tree-sprigs when you estimate the size of the index. Each sprig uses no more than a single 4 KiB chunk. Also, verify that all index entries are stored at the desired fill fraction, which defines the level to which a sprig is filled. This allows for some expansion without overfilling and consuming more than one chunk per sprig. See the Capacity Planning Guide for more information.

error sending exchange dataFailure exchanging partition maps with another node because the node is down or disconnected from the network and unable to receive messages.
received duplicate exchange data from node 783f4ac2fbb57e81Another node has resent exchange data because it did not receive an acknowledgment from this node within half the heartbeat interval. This is most likely due to a networking issue.
node
NodeID of the origin of the unacknowledged exchange data
received duplicate ready to commit message from node 783f4ac2fbb57e81A node has resent the ready to commit message because it did not receive an acknowledgment from this node within half the heartbeat interval. This is most likely due to a networking issue between nodes in the cluster. Those ready to commit messages are sent by each node to the principal node when the exchange data has been completed on the node. The principal node also follows this pattern and sends itself such a ready to commit message. On a given node, the exchange data is done when the node has successfully sent its partition map to all the nodes in the cluster as well as received the partition map from each node in the cluster. This requires each node to ack back that it has received the exchange data. Only then would a node tell the principal that it is ready to commit. While the principal is waiting to receive the ready to commit from some nodes, other nodes would keep sending their ready to commit as they are ready and waiting. Therefore, the nodes for which such message is seen are the nodes that are ready and the other nodes would be the ones having potential issues completed their exchange data.
node
Node ID of the node that is continuing to send the ready to commit message as it is waiting for the principal to acknowledge.

migrate: unreadable digestAppears on the source node when the record could not be read locally. Introduced with Database 6.0. Associated with the handle insert: got no record warning.
missing acks from node BB9030011AC4202This means that a particular migration thread has begun to throttle because it has 16MB or more of un-acknowledged records, and has remained in that state for at least 5 seconds. The message prints every 5 seconds until the outstanding acks drop below the threshold. This happens when migration has been pushed higher than your network or machine/disks can sustain. To mitigate, decrease migrate-threads down to a minimum of 1. This change does not take effect immediately; threads terminate as the partition they are handling completes migration. This warning could also be triggered if channel-bulk-recv-threads was reduced during ongoing migrations.

ns can’t attach persistent memory base block: block does not existA missing shared memory block. This typically happens when a node is rebooted, but shared memory blocks can be deleted for other reasons. The node must perform a cold start.
{ns_name} found no valid persistent memory blocks, will cold starttreex and base shared memory blocks are missing. This typically happens when a node is rebooted or after an ungraceful shutdown. The node must perform a cold start.
{ns_name} persisted arena stagesThis message is one of a sequence of messages logged during Aerospike server shutdown of storage-engine device namespaces. The message signifies that the arena stages for the namespace have been persisted to storage. An unusual delay in the appearance of this message during shutdown might be due to index-type configured to pmem.
{ns_name} persisted tree rootsThis message is one of a sequence of messages logged during Aerospike server shutdown of storage-engine device namespaces. The message signifies that the namespace’s common partition index tree information has been persisted to storage. An unusual delay in the appearance of this message during shutdown might be due to a high number of partition-tree-sprigs configured for the namespace.
{ns_name} persisted trusted base blockThis message is one of a sequence of messages logged during Aerospike server shutdown of storage-engine device namespaces. The message signifies that the persistent memory base block for the namespace has been persisted to storage with “trusted” status. “trusted” status is a necessary condition for a subsequent fast restart of the namespace.

{namespace} failed set evict-void-time 328967879When high-water-disk-pct, high-water-memory-pct, or mounts-high-water-pct is breached on any node and eviction starts, the timestamp before which records need to be evicted is propagated to all nodes through the System Meta Data (SMD) mechanism, to ensure that no orphaned replicas are left anywhere in the cluster. If not all nodes have acknowledged the message within 5 seconds, this message is logged. Occasional instances of this message do not indicate a serious problem, as the timestamp is picked up on the next namespace supervisor (nsup) cycle.

Partition
{ns_name} 2 of 5 nodes are quiescedNumber of nodes quiesced in the cluster (or sub cluster).
When the cluster changes (node addition, removal, or network splits) or when the cluster receives a ‘recluster’ info command.
nodes participating
The number of nodes quiesced in this sub-cluster out of the total number of nodes observed in the sub-cluster. For strong-consistency namespaces, it is full roster size instead of observed in the sub-cluster.
{ns_name} 5 of 6 nodes participating - regime 221 -> 223Number of nodes participating in the cluster (or sub cluster) as well as the regime change.
For strong-consistency namespaces, when the cluster changes, because of node(s) leaving or joining the cluster (or network splits).
nodes participating
The number of nodes participating in this cluster out of the total number of nodes for the full roster.

This number increments every time there is a reclustering event. This is used in strong consistent namespace and is leveraged by the client libraries. For further details on regime, see Strong consistency.
{ns_name} rebalanced: expected-migrations (1215,1224,1215) fresh-partitions 397Number of partitions expected to migrate (transmitted, received, and signals) as well as other migration related statistics and fresh partition number.
For non strong-consistency namespaces, when the cluster changes, because of node addition, removal or network splits.
expected-migrations
The number of partitions expected to migrate (Transmitted, Received, Signals) as part of this reclustering event. Those correspond to the migrate_tx_partitions_initial, migrate_rx_partitions_initial, and migrate_signals_remaining statistics respectively.
fresh-partitions
Number of partitions that are created fresh or empty because a number of nodes, greater than the replication factor, has left the cluster.

The number of partitions expected to migrate (Transmitted, Received, Signals) as part of this reclustering event. Those correspond to the migrate_tx_partitions_initial, migrate_rx_partitions_initial, and migrate_signals_remaining statistics respectively.
expected-appeals
The number of appeals expected as part of this reclustering event. Appeals occur after a node has been cold-started. The replication state of each record is lost on cold-start and all records must assume an unreplicated state. An appeal resolves replication state from the partition’s acting master. These are important for performance; an unreplicated record must re-replicate to be read, which adds latency. During a rolling cold-restart, an operator may want to wait for the appeal phase to complete after each restart to minimize the performance impact of the procedure. Corresponds to the appeals_tx_remaining statistic but only at the initial time of the reclustering event.
unavailable-partitions
The number of partitions that are unavailable as the roster is not complete and all writes that have occurred to those partitions are not present. Partitions remaining unavailable after the cluster is formed by the full roster become dead and require the use of the revive command to make them available again, which could lead to inconsistencies, depending on what lead to those partition being dead. Revived nodes restore availability only when all nodes are trusted. Corresponds to the unavailable_partitions statistic.

Possibly a primary index and corresponding record got deleted, but the secondary index still exists. Subsequent round of garbage collection may correct the tree structure. May mean that partial results were returned during the query. If seen frequently, may mean that there is a structural issue with the secondary index. In this case, drop and re-create the index.

Normally this would never happen, but there was a bug in some older database Databases whereby this mismatch could occur when a node containing old data was cold-started and brought back into the cluster with records that had been deleted but not durably deleted. This was corrected in Database 4.4.0.8 and later. Enterprise Edition Licensees can contact Aerospike Support for further guidance when encountering this error.

write_master: disallowed ttl with nsup-period 0When expirations in a namespace are disabled because nsup-period is set to the default of 0, records with a TTL other than 0 may not be written to that namespace. This is to avoid confusion as to whether the records should be subject to expiration (or eviction). Simply set the nsup-period to a value other than 0 to allow records with a TTL other than 0 to be written. If there is a need to allow records with a non 0 TTL without having the nsup thread running, it is possible to set ‘allow-ttl-without-nsup` to true, but this is not recommended prevents those records from being properly deleted upon expiration.

scan msg from 10.11.12.13 has unrecognized set name_of_the_setA scan specifying an unknown set was received.

For example, a set with fewer records than the number of nodes in the cluster, where some nodes don’t hold any record (master or replica) for that set. Having something configured for the set, such as access control that is set specific or a secondary index definition, causes this log warning message to disappear as the set would then be ‘known’ on the node even without any record in it.

Security
FAILED ASSERTION (namespace): (namespace_ee.c:550) can't remove persistent memory base block: Operation not permittedWhen running under systemd, this error occurs if shared memory has been allocated by a previous user, and a second user who does not have privileges to access those shared memory segments starts the Aerospike server. Aerospike reads the user from the aerospike.conf file; however, if the shared memory segments are still allocated by the previous user, it may be necessary to force a cold start.
WARNING (security): (security.c:857) unknown security message command 20Clients that enable the LDAP protocol server-side, and run on Databases of Aerospike that did not support server-side LDAP, may see this warning when they attempt to log in. This warning is transitory as the server falls back to use the non-LDAP protocol by default. Check the release notes of each client to validate the Database that supports LDAP.

login - internal user credential mismatchProvides a warning that a login failed using a valid internal user that is found in the access control list with an incorrect password.
Occurs when a failed login is attempted using an internal user that exists in the access control list but where an incorrect password has been supplied.
login - internal user not foundProvides a warning that a login failed with an internal user that is not found in the access control list.
Occurs when a failed login is attempted with an internal user that is not found in the access control list. To log the details of the internal user that is not found, report-authentication and report-violation must be set to true. See Security Configuration for details.
login - internal user using ldapA login failed with an internal user that is not found in the access control list.
Occurs when a login attempt fails with an internal user that is not found in the access control list. Some conditions when the warning message is presented to the user while incorporating the use of an ACL.
- When an encrypted ‘external’ (clear password encrypted) is used for LDAP but a stored hashed ‘internal’ password also exists for that user.
- When an incompatible Aerospike client is attempting to connect to Database 4.6 or newer. See
Overview of Access Control with LDAP and PKIfor details to ensure you are using a compatible Aerospike client version. - When clusters using Cross-Datacenter Replication (XDR) are running with conflicting Aerospike Database versions. When running XDR and an ACL, Database versions 4.1.0.1 to 4.3.0.6 are incompatible with Database 4.6 or later. The incompatible Database versions 4.1.0.1 to 4.3.0.6 cannot ship to 4.6.0.2 or later. The simplest workaround is to avoid using versions 4.1.0.1 to 4.3.0.6. See Internal user warning returned for details.
This warning message typically appears in the logs when upgrading a cluster.

Service
refusing client connection - proto-fd-max 50000The server has reached the configured maximum for incoming file descriptors (proto-fd-max). This corresponds directly to incoming client connections. Connections greater than the maximum are refused.
proto-fd-max
Currently configured value for proto-fd-max
unsupported proto version 0 from 12.0.0.1:5598Indicates that messages of an unexpected type are being sent to the main server port (usually port 3000) by other nodes in the cluster. This can happen if the nodes have been misconfigured to use the main server port instead of the correct port. For example, the configuration for Mesh heartbeats should specify port 3002, not port 3000.

Socket
Error while adding FD <FD> to epoll instance <Poll-FD>: <error-code> (<error-string>)A double-close of file descriptors can lead to this assertion under certain conditions. If a file descriptor (FD) is closed twice in rapid succession, it usually fails silently after the first successful close. However, if the FD is reused between the first and second close due to a race condition, the second close could mistakenly target an active connection. This can result in errors like “Bad file descriptor” when the reused FD is assigned to a service thread’s epoll instance.
Example: Error while adding FD 2817 to epoll instance 1105: 9 (Bad file descriptor)
See this Bad File Descriptor knowledge base article for details on one known cause of this assertion when using multiple LDAP servers in the Aerospike configuration and at least one of them is failing to connect against.

Truncate
{ns-name} done truncate to T deleted NThis message indicates a request to truncate up to timestamp T has finished, after deleting N objects.
Truncate process completed.
{ns-name} done truncateTruncate command completed.
{ns-name} flagging truncate to restartNamespace needs a second truncation pass through after the current pass completes. Truncation can act on more than one set at a time so if a truncate command is received for a set in a namespace that is currently already going through truncation (for a different set for example), a subsequent iteration is required. For example, a truncate against set s2 is ongoing when a truncate command against set s4 is triggered. In this case, from the moment the log message appears (when the command to truncate against set4 is issued), both set2 and set4 are truncated together until the end of the current pass. Then truncation restarts another pass through the namespace, so that the rest of set4 gets truncated.
{ns-name} starting truncateTruncate command being processed for the namespace.
{ns-name} truncated records (10,50)Truncate command being processed for the namespace.
(current,total)
Current truncation count (10 in this example) followed by the total number of records have been deleted by truncation since the server started (50 in this example). Those counts are only kept at the namespace level.
{ns-name|set-name} got command to truncate to now (226886718769)Truncate command received. Appears on the node where the info command was issued. The command is distributed to other nodes using system metadata (SMD), and only the truncating/starting/restarting/truncated/done log entries appear on those nodes.
(timestamp)
The LUT time in milliseconds since the Citrusleaf epoch (00:00:00 UTC on 1 Jan 2010).
{ns-name|set-name} tombstone covers no records on this nodeOccurs at cold start-up and is a listing of all set truncations found in the truncation SMD file (System Meta Data) that are not covering any records. The internal mechanism is that all set truncation tombstones are marked as cenotaph before records are read from drive to build the index. The term tombstone refers here to such a truncation related entry, not to be confused with record level tombstones. We only cycle through those tombstones one time for a namespace during a cold-start. If the drives are all fresh, there is a cenotaph log message for every set truncation in SMD. After the drives are read, which could potentially restore records from truncated sets and strip a set-covering tombstone of its cenotaph status, all the set-truncation tombstones that are still cenotaphs (not covering any tombstones) are listed.

Tsvc
rejecting client transaction - initial partition balance unresolvedWhen using some older Aerospike Client Libraries, there is a very small window where a node joins a cluster and other nodes begin to advertise the node but the node hasn’t finished creating its partition table and a client picked up that advertised service and made a request. This message happens only during that window and should resolve on its own very quickly.
transaction is neither read nor write - unexpectedAn invalid request has been received, either a read/write request where the corresponding bit is not set, or an operate() command with no operations. The error code -4 (FAIL_PARAMETER) is returned to the client if there is one, but this message can also be caused by non-Aerospike traffic reaching the service port.

This warning can also happen if there is a connection reset while trying to read from the socket. A potential cause could be the remote side having a node being restarted.
connected to <DCNAME> <xx.xx.xx.xx>:<xxxx>This is logged on a source node whenever the xdr-client tend thread establishes a successful connection to the destination node. The line is logged under the following conditions:
- The first time the tend thread successfully connects to the destination node. If security is enabled on the destination, the login only happens if security is enabled in the configuration.
- The tend thread has to re-establish the connection again as the login attempt failed when security was enabled on the destination node.
- The tend thread has to re-establish the connection in cases such as source or destination restart, or any network interruption. The login flow can be found at XDR login flow.

The server (destination node) sets the expiry of the access token, provided to the xdr-client, a minute shorter than the actual expiration time (renewal margin). The xdr-client tend thread refreshes the token one minute before its actual set expiry. It means the source node is issuing a LOGIN command to refresh its token for the specified destination DC node (IP:port). The login flow can be found at XDR login flow.

The namespace where the set could not be created.
XDR digestlog cannot keep up with writes. Dropping record.Aerospike is writing data faster to the XDR digestlog than the underlying disk can handle. If using raw-disk backed xdr storage, consider switching over to file-backed xdr storage for the xdr-digestlog-path parameter. This takes advantage of filesystem caching for reads and writes. Otherwise, you may need to use a faster disk or join multiple disks using RAID-0 to allow for faster read/write to the XDR digestlog. Also ensure that dmesg is properly checked for disk failures and a SMART disk test is performed.
'XXXX' cluster does not support pipeliningThis message usually indicates that one of the destinations is running an older version of XDR (pre-3.8) or there exists a misconfiguration of the kernel configs /proc/sys/net/core/wmem_max and /proc/sys/net/core/rmem_max between source and destination clusters.

The cumulative number of records that have been attempted to be shipped since this node started, across all datacenters. If a record is shipped to 3 different datacenters, then this number increments by 3. Corresponds to the sum of the xdr_ship_success, xdr_ship_source_error and xdr_ship_destination_error statistics.
ul
The number of record’s digests that have been written to the node but not logged yet to the digestlog (unlogged).
lg
The number of record’s digests that have been logged. Includes both master and replica records but a node only ships records when it owns the master partition and processes records belonging to its replica partitions only when a neighboring source node goes down.
rlog
Relogged digests. The number of record’s digests that have been relogged on this node due to temporary failures when attempting to ship. Corresponds to the dlog_relogged statistic.
rlgi
Relogged incoming digests. The number of record’s digest that another node sent to this node (typically prole side relog or partition ownership change). Corresponds to the relogged_incoming statistic.
rlgo
Relogged outgoing digests. The number of record’s digest log entries that were sent to another node (typically prole side relog or partition ownership change). Corresponds to the relogged_outgoing statistic.
lproc
The number of record’s digests that have been processed locally. A processed digest does not necessarily imply a shipped record (for example, replica digests don’t get shipped unless a source node is down, and hotkeys also don’t have all their updates necessarily shipped). Corresponds to the dlog_processed_main statistics.
rproc
The number of replica record’s digests that have been processed by this node. A node processes records belonging to its replica partitions only when a neighboring source node goes down. Corresponds to the dlog_processed_replica statistic.
lkdproc
The number of record’s digests that have been processed as part of a linked down session. A link down session is spawned when a full destination cluster is down or not reachable. Corresponds to the dlog_processed_link_down statistic.
errcl
The number of errors encountered when attempting to ship due to the embedded client. For example, if the local XDR embedded client is having issues or delays in establishing connections. Corresponds to the xdr_ship_source_error statistic.
errsrv
The number of errors encountered when attempting to ship due to the destination cluster. For example if the destination cluster is temporarily overloaded. Corresponds to the xdr_ship_destination_error statistic.
hkskip
Hotkey skipped. Represents the number of record’s digests that are skipped due to an already existing entry in the reader’s thread cache (meaning a version of this record was just shipped). Corresponds to the xdr_hotkey_skip statistic.
hkf
Hotkey fetched. Represents the number of record’s digest that are actually fetched and shipped because their cache entries expired and were dirty. Corresponds to the xdr_hotkey_fetch statistics.
flat
The average time in milliseconds to fetch records locally (this is an exponential moving average - 95/5). Corresponds to the xdr_read_latency_avg statistic.
dlog: free-pct 93 reclaimed 2456 glst 1490623097271 (2017-03-27 13:58:17 GMT)Provides digest log (dlog) related information.
Every 1 minute.
free-pct
Percentage of the digest log free and available for use. Corresponds to the dlog_free_pct statistic.
reclaimed
Indicates how many digests were safely ‘removed’ from the digestlog. As shipping successfully proceeds, and records are shipped, digests which are no longer necessary can have their space reclaimed in the digest log. A linked down (destination cluster down or unreachable) is an example where digest log space cannot be reclaimed.
glst
The minimum last ship time across all nodes in the cluster. Corresponds to the xdr_global_lastshiptime statistics. This specifies up to what point slots in the digest log can be reclaimed, by keeping track of the oldest last ship time across all nodes in the cluster.
dlog-q: capacity 64 used-elements 1 read-offset 0 write-offset 1Status information on the dlog-q. The dlog-q queue is the in-memory digest log queue. Digests of records that have been written get put on this in-memory queue. The dlogwriter picks them from there and puts them in the on-disk digest log. See below for the details on the 4 numbers.
Every 1 minute.
capacity
The size of the queue.
used-elements
The number of elements in the queue.
read-offset
The read pointer of the queue. In general, the number of elements in the queue is the difference between the read pointer and the write pointer (that is, the number of elements that have been written to the queue but haven’t yet been read).
write-offset
The write pointer of the queue. In general, the number of elements in the queue is the difference between the read pointer and the write pointer (that is, the number of elements that have been written to the queue but haven’t yet been read).

XDR tomb raider has finished its cycle that is expected to run every xdr-tomb-raider-period seconds having dropped n records and took t ms to finish.
n
Number of records dropped by the current cycle of XDR tomb raider.
t
Number of ms XDR tomb raider cycle took to finish.
{namespaceName} DC DC1 abandon result -4In strong-consistency enabled namespaces, if XDR finds a record which has not been replicated, re-replication from master to replica is triggered. XDR prints this warning message when this happens. XDR attempts to ship that record again. See XDR transaction delays for details on how XDR handles record in strong-consistency enabled namespaces. See XDR 5.0 Error codes.
summary: throughput 3722 inflight 164 dlog-outstanding 100 dlog-delta-per-sec -10.0throughput
The current throughput, shipping to destination cluster(s). When shipping to multiple clusters, the throughput represents the combined throughput to all destination clusters. Corresponds to the xdr_throughput statistic.
inflight
The number of records that are inflight, meaning that have been sent to the destination cluster(s) but for which a response has not been received yet. Corresponds to the xdr_ship_inflight_objects statistic.
dlog-outstanding
The number of record’s digests yet to be processed in the digest log. In parenthesis, the average change normalized to digests per second over the 10 seconds interval separating those log lines. Corresponds to the xdr_ship_outstanding_objects statistic.
dlog-delta-per-sec
The variation of the dlog-outstanding normalized on a per second basis. Gives an idea whether the number of entries in the digestlog is increasing or decreasing over time and at what pace.
