Out of memory

[jarome]

When I try to clean up the database in the settings menu, I get an out of memory error. I told Subsonic to use 2000 MB in /etc/sysconfig/subsonic. It is not able to scan my collection of 71000+ tracks. It seems stuck at 21,000 or so.

The problem is that the server does not shut down, even though it says it does. There are multiple Java processes still running (same PID, but different ports). I have to kill these manually, and also the db lck file.
Why doesn't subsonic close down properly? OpenSUSE 13.2
