---------------------------------------
Resolution: Not A Problem

> KahaDB not cleaning journal db-<id>.log files
> ---------------------------------------------
>
> Key: AMQ-8373
> URL: https://issues.apache.org/jira/browse/AMQ-8373
> Project: ActiveMQ
> Issue Type: Bug
> Components: AMQP
> Affects Versions: 5.14.4
> Environment: ActiveMQ 5.14.4
> Reporter: Sandeep Singh
> Priority: Major
>
> Application is running continuously initially files were cleaned up but after
> some time they start pilling up and killing the file system.
> Once I turn on trace logging for
> org.apache.activemq.store.kahadb.MessageDatabase, it
> shows below information about the files it is checking during the garbage
> collection process. All are blocked for acknowledgement.
> Kindly suggest if there is any way to clean these old files.
