Subject [jira] Commented: (AMQ-2736) KahaDB doesn't clean up old files
Date Tue, 16 Nov 2010 14:17:30 GMT

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

Use Jeff's patch for 5.4.1, http://people.apache.org/~jgenender/apache-activemq-5.4.1-AMQ2736-AMQ2982-AMQ2983-AMQ2935-bin.tar.gz

I deployed it in production today and it totally removed the problem with growing log files.
It went down from 78 log files to just 1 log file.

> 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.
