Hiram Chirino commented on AMQ-5404:
------------------------------------
LevelDB is keeping a log file read cache sized to 100. On a file delete, it's
not taking it out of the cache.
> LevelDB files not being released after deletion
> -----------------------------------------------

> Key: AMQ-5404
> URL: https://issues.apache.org/jira/browse/AMQ-5404
> Project: ActiveMQ
> Issue Type: Bug
> Reporter: Scott Benson
>
> During numerous test runs we've seen the file system fill up (df -k) and
> eventually ActiveMQ failing with a short write error. When ActiveMQ falls
> over the file system is freed up to its original state.
> Before ActiveMQ falls over we've tried to find the reason for the file system
> filling up by hunting through the directories but to no avail. However when
> we do a lsof -a +L1 we can see numerous deleted LevelDB log and index files.
>
> Does anybody know why ActiveMQ/LevelDB is not releasing these files for full
> clear up by the OS.
> This is on
> Red Hat Linux 6.4
> ActiveMQ 5.10
> Java 1.7.0_45
