Original issue 839 created by arlake228 on 2014-02-11T16:31:21.000Z:

If powstream dies in the middle of a test, it will leave a session file lying around. Theoretically, the client could later come and collect that file, but in practice, he won't, and this can leave a large number of session files sitting around taking up the limited 'disk' space from whatever limit they were classified as.

This can be worked around by deleting old files and restarting owampd, but that can have adverse effects on any tests currently running.

The daemon should include an option for cleaning up old session files.

In the toolkit, we've put in a place a system that uses find to clear out old session files, and then restarts owampd. This fixes the issue; however, having this done by owampd proper, would be better.

Note: this is related to issue 1068, and should probably be worked on at the same time.

I'm not sure the master owampd process know which files were created by the children in order to clean them up later.

How about we create a cron job that would remove files older than one day and not open by any current owampd process? After that we remove any old broken symlinks from the catalog directory. This would not require a restart of the owampd process and stop active sessions.
