Hi, We are having some issues with kahadb. We see that some journal files, named "db-", are not removed and this makes ActiveMQ to use a lot of disk space.
We've activated ActiveMQ logs and there are some logs with this information: 2018-04-23 11:32:52,218 [eckpoint Worker] TRACE MessageDatabase - not removing data file: 348 as contained ack(s) refer to referenced file: [348, 234] 2018-04-23 11:32:52,218 [eckpoint Worker] TRACE MessageDatabase - not removing data file: 357 as contained ack(s) refer to referenced file: [356, 357] 2018-04-23 11:32:52,218 [eckpoint Worker] TRACE MessageDatabase - not removing data file: 369 as contained ack(s) refer to referenced file: [368, 369] 2018-04-23 11:32:52,218 [eckpoint Worker] TRACE MessageDatabase - not removing data file: 370 as contained ack(s) refer to referenced file: [369, 370] 2018-04-23 11:32:52,218 [eckpoint Worker] TRACE MessageDatabase - not removing data file: 371 as contained ack(s) refer to referenced file: [370, 371] 2018-04-23 11:32:52,218 [eckpoint Worker] TRACE MessageDatabase - not removing data file: 372 as contained ack(s) refer to referenced file: [372, 371] 2018-04-23 11:32:52,218 [eckpoint Worker] TRACE MessageDatabase - not removing data file: 396 as contained ack(s) refer to referenced file: [396, 395] I know that a journal file is not removed until all its messaged are ACKed. However, I don't understand the meaning of this message: *not removing data file: X as contained ack(s) refer to referenced file: [X, Y]* Apparently the journal file with X id is not removed because it contains messages with references to another journal file. I don't understand how this can be possible. I've searched information about this message but I haven't found a clear answer. Could you point me to a resource with information about this? Thanks in advance. Iñigo -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
