Subject [jira] Commented: (AMQ-2736) KahaDB doesn't clean up old files
Date Tue, 09 Nov 2010 07:52:06 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-2736?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=63192#action_63192

Christer WIkman commented on AMQ-2736:
--------------------------------------

I deployed yesterday in stage latest 5.5-SNAPSHOT and it seems that the problem is solved.
This morning I had 17 log files, but after I deleted DLQ queues with messages I ended up with
only 1 log file! When I used 5.4.1 the files grow with approx 50-100 files per day. 

We are not comfortable deploying 5.5-SNAPSHOT in production. Can anyone provide me with a
patch for 5.4.1? Currently, I cannot recommend using version 5.4.1 in production without the
combined fixes from 5.5-SNAPSHOT.

> 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.
