Addition: I killed the hanging process with kill -3 and got a stackdump this time. It's attached. Lambertus wrote:
Well, you are probably right in that the Java VM itself in hanging: The process hung again and jstack reports: "Unable to open socket file: target process not responding or HotSpot VM not loaded".
Forcing it to attach gave an error about HotSpot not being able to find a "Symbol". Anyway, I guess it's time to move to another Java VM...

The error files were produced using kill -4<pid>. Kill -1 till -3 had no effect on the process. Just switching to using Sun Java is probably That would explain it then :) But -3 should have caused java to write out the stack traces onto standard output. If you would have seen that but didn't that would also lend support to the idea that java itself was hung.
