I simply have
<persistenceAdapter>
<kahaDB cleanupInterval="30000" journalMaxFileLength="32mb"
directory="${karaf.data}/activemq/default/kahadb"/>
</persistenceAdapter>
As my kahaDB configuration inside of the activemq-broker.xml file. This
configuration still allows for indefinite growth.
The sad thing is that I can fix this simply by shutting down ServiceMix and
deleting the data directory, but I'm trying to prevent an interruption of
service.

Thank you for the reply Jon. I added trace logging and see kahadb logs to the
tune of
2012-02-20 17:26:45,707 [eckpoint Worker] DEBUG MessageDatabase
- Checkpoint started.

- Checkpoint done.
Which to me looks like there is not a lot of work hanging around, but there are
TONS of files still piling up with 32 megs of usage on each one. I'm using the
ActiveMQ 5.4.2 bundles.
Are there additional settings I should try? I'm looking for docs/bug
reports/anything that can help me figure out how to keep this from grown
indefinitely. What really stinks is that even after a restart, these files
persist.
Thanks,
Zach Calvert

If you just send messages to a queue and do not consume those messages, then
they would be kept around. Is this the case? You may want to read this
too:
