Oplog gap detected during creation of update packet

When running syncreplica –export, a warning that the command found a different oplog ID than expected can indicate a serious error, involving an unrecoverable data loss.

syncreplica –export can fail with the following warning message:
Gap in oplog detected for replica replica-name.
Wanted oplog id: oplog-ID. Got oplog id: oplog-ID.

If the procedures described in Cannot find oplog entry do not work, contact HCL Customer Support.
