MongoDB Error 259: Keyed Executor Retry
Description
Error 259, 'Keyed Executor Retry', indicates that an internal MongoDB operation managed by a 'keyed executor' component encountered a transient issue and is attempting to retry. This often occurs in distributed deployments like sharded clusters or replica sets when the system needs to re-evaluate or re-execute an operation due to temporary inconsistencies or resource unavailability.
Error Message
Keyed Executor Retry
Known Causes
4 known causesTransient Network Instability
Brief interruptions or high latency in network communication between MongoDB instances (e.g., replica set members, config servers, or shards) can trigger internal retries.
Resource Contention
High CPU, memory, or disk I/O utilization on a MongoDB server can lead to operations timing out or being delayed, prompting the keyed executor to retry the operation.
Cluster Topology Changes
Events such as replica set primary elections, shard rebalancing, or migrations can temporarily disrupt operations, causing the system to retry until the new topology stabilizes.
Stale or Inconsistent Metadata
In sharded clusters, temporary inconsistencies in configuration metadata can lead to operations being retried until the metadata is synchronized across the cluster.
