Java tmpdir?

Hi, recycling a question. We are using Druid, but it seems it is filling up /tmp in our -Djava.io.tmpdir option to rather large sizes without cleaning up. Has anyone encountered this, and perhaps recommend a way to clean it up?

It makes it a pain to monitor disk sizes of hosts.

Okay, so if anyone runs into the issue the best solution I have at the moment is running a nightly (midnight) cron job that cleans up old /mnt/tmp/base* files that are written to the path of your Java tmpdir flag.
