Subject [jira] Commented: (AMQ-2736) KahaDB doesn't clean up old files
Date Tue, 16 Nov 2010 13:59:30 GMT

Adrian Lisenberg commented on AMQ-2736:
---------------------------------------

Hi, I really need this fix!!!!. So finally you tested the fix on 5.4.1 or you are going to
put 5.5 in production? 

excuse me, but which is the file with the correct patch?

One more question: After applying this fix, would be any way for deleting old log files in
order to reduce unused space? I am at 100G and I need to maintain the current state of the
broker...

thanks.

> 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.
