Subject [jira] Reopened: (AMQ-2736) KahaDB doesn't clean up old files
Date Fri, 17 Sep 2010 06:10:40 GMT


Straun reopened AMQ-2736:

I am seeing this with a broker holding transactional persistent messages (100k messages a
day 10k per msg), the queue sizes are all around 0 normally so I would expect the files to
be cleared. I am using 5.4.0. The consumer of the messages is a .Net client with 'auto acknowledge'
set. The KahaDB also appears to slow down as it runs, writes to the queues slows down so that
the each commit cycle is taking 10% longer than the last.

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
