Description

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
