Nandkishore Singh commented on AMQ-5695:
----------------------------------------
Gary, It was not easy for us to capture the sequence of events in to a smaller
test. The question is, When activemq creates a new journal log after the
threshold limit of 32 MB, What happens to the messages in the journal log for
which it has not received an ACK yet. Does it move these messages to the new
journal.
> KahaDB not cleaning up log files
> --------------------------------
>
> Key: AMQ-5695
> URL: https://issues.apache.org/jira/browse/AMQ-5695
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.11.1
> Reporter: Stefan Warten
> Assignee: Arthur Naseef
>
> Since we have upgraded ActiveMQ from 5.10.0 to 5.11.1, KahaDB is not cleaning
> up log files properly. It seems to keep all of them. It helped once to
> restart the service and minutes later, ActiveMQ cleaned up 95% of log files
> but mostly it is not cleaning up at all.
> When partition was full, I stopped ActiveMQ, copied the KahaDB to another
> host and started it with empty queues again. Then I forwarded all messages
> from that other host back. Even when all messages were forwarded and all
> queues were empty, the old KahaDB log files were not cleaned up.
> I stopped ActiveMQ, removed db.data and db.redo to rebuild index which took
> around 3h (350GB of log files) but still, the log files are not cleaned up.
