Subject: Java Zombies

Another strange behaviour...

I just got back into my java code and experienced really strange things:

I run a java app for a while, stop it, start it, do things with it
(development tasks...) and suddenly java becomes defunct.

all running java processes are zombies and no trick will kill them. java gui
stays onscreen but doesen't refresh.

and, even more strange: while CPUs stay at about 2 to 8% activity load
increases. it's at 7 now after around 2 minutes

I attach some info about my system (X60s 1702-55G)

oops: cat /proc/cpuinfo hangs!!

...after that I could not even shutdown cleanly.
I had to use SysRq keys to halt the system
