> This issue is being spawned from a comment in AMQ-2736:
> "I have a queue that holds onto a message every once in a while due to bad formatting or what-have-you (not something I can immediately correct). Since KahaDB requires the need to retain the full contents of the DB file while one message persists, it will cause the file system to grow dramatically if you alter the default kahaDB file size at all. With a DB file of 96 megs each I've eaten up almost 5 gigs of disk space in 34 pending messages all less than 2000 bytes each.
> I'm going to begin auto purging the offending queue (since we don't require those messages), however it would be preferred to have some automatic process possibly automatically consolidate the DB once its reached a pre-configured limit?"
> So, I'd like to officially request some sort of consolidation or 'garbage collection' of kahadb files when the storage footprint reaches a preconfigured limit, allowing the ActiveMQ system to clean itself up and prevent overflowing disk space with pending messages that may never get processed.
> Please let me know if you have any questions or need any further information. Thanks!
