Christer WIkman reopened AMQ-2736:
----------------------------------


We running: http://people.apache.org/~jgenender/apache-activemq-5.4.1-AMQ2736-bin.tar.gz and
we are still experience problems with log files that are not deleted. 

I deployed the fix yesterday with a new kahadb and this morning I had 155 log files with only
43 messages on two DLQ queues. I deleted the DLQ queues and only 12 log files where deleted.
Currently,. I have 144 log files and nothing in the queues.

> Over time, we're seeing that kahadb doesn't clean up old journal files. As a result,
we eventually run out of disk space, or rather, we hit our usage limits and our producers
are slowed down by the producer flow control mechanism. Others have experienced this problem
too (for example, see http://mail-archives.apache.org/mod_mbox/activemq-users/201002.mbox/%3C27502591.post@talk.nabble.com%3E)
> For now, we're moving back to the old amqPersistenceStore.
