Subject [jira] Commented: (AMQ-2736) KahaDB doesn't clean up old files

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

@Jeff - Thanks! I have deployed your fix in our stage environment. It works much better but
not 100%. All queues are empty but I still have 4 log files and one contains 0 bytes, last
updated yesterday, and other log file was last updated 6 hours ago. When I used 5.5-SNAPSHOT
it went down to 1 log file!

I will evaluate it for some more days before I can tell for sure if the log files grows.

> 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.
