Description

On an idle broker stop, two artefacts are synced to the journal via checkpoint, one restart the recovery checking verifies the ordered replay of these artefacts. However if there has been no message send since the last update the audit artefact is not written and recovery believes in error that it needs to replay records. This process creates unnecessary logging and can slow restart along with causing alarm.

INFO: Recovery replayed X operations from the journal in Y seconds.
