MongoDB Error 152: Oplog Order Inconsistency
Description
Error 152, 'Oplog Out Of Order', indicates a critical issue within a MongoDB replica set where the operations log (oplog) entries are not in the expected chronological sequence. This typically disrupts replication and prevents secondary members from synchronizing correctly with the primary.
Error Message
Oplog Out Of Order
Known Causes
4 known causesClock Skew Between Members
Significant time differences between replica set members can cause operations to be recorded with timestamps that appear out of order when viewed by other members.
Oplog Corruption or Manual Intervention
Direct manipulation, file system errors, or data corruption can lead to the oplog containing inconsistent or incorrectly ordered entries.
Network Latency or Instability
High network latency or intermittent connectivity can cause operations to arrive and be processed by different members in an unexpected sequence.
Unexpected Server Shutdowns
Abrupt termination of MongoDB processes or server crashes can leave the oplog in an inconsistent state upon restart, especially if writes were in progress.
