             Summary: KahaDb recover from corrupt metadata state locations that can be rebuilt
                 Key: AMQ-6378
                 URL: https://issues.apache.org/jira/browse/AMQ-6378
             Project: ActiveMQ
          Issue Type: Bug
          Components: Message Store
    Affects Versions: 5.13.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.14.0


The index tracks producerAudit and ackMessageFileMap locations. Failure to recreate/read on startup can be replayed from the journal however if the locations are corrupt the broker errors out. In this case a replay can still recreate this information.
