Re: KahaDB data files not cleaned up
A bit more info on older kahadb journal files. I checked and they are not
open by any process. Deleting them frees up disk space.
If I don't need older messages is it ok to delete old kahadb files or will
it cause problems to the broker?
Is there a tool to read these files to find out which message(s) prevent it
from being cleaned up?
Thank you

Gary,
I got 11 files from April 5 (db-9.log - db-19.log), 9 files from April 7
(db-301.log, db-303.log - db-310.log) and one with the current time stamp of
April 12 (db-681.log). Time to live is 2 hours so April 5-7 files are not
expected to be there.
It's now running with debug traces and I'll look for cleanup-related
messages.
Thank you

To my knowledge 5.5 resolves all know issues with data file cleanup. One
case where seemingly un referenced files remain is where they contain acks
to messages in other data files, so their removal could result in duplicate
delivery on recovery.
There is now detailed trace log messages from the journal that describes the
cleanup process wrt destinations.

This is something that affects some of my installations.
Is there any reason not to delete a file that should have been removed by now?
