Timothy Bish closed AMQ-4838.
-----------------------------
Resolution: Cannot Reproduce
Not test case or other logs to look at, many fixes in KahaDB since 5.8.0
probably already addressed the issue here.

> Key: AMQ-4838
> URL: https://issues.apache.org/jira/browse/AMQ-4838
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.8.0
> Environment: Standalone single ActiveMQ 5.8.0, Linux
> Reporter: Ron Koerner
> Priority: Critical
>
> I got this exception out of the blue on a standalone ActiveMQ broker which
> was running for 8 days at that time. I set the priority to critical as we
> lost a lot of data due to this bug.
