Thomas Frössman commented on RF-7927:
-------------------------------------

It worked all day but now it's back :(
Before the kernel downgrade we could reproduce it at every start of jboss just doing a few uploads so it is working better now but far from perfect.
We don't see this problem on our production servers which are using the same versions of richfaces and jboss and jvm (1.6.0_16).
The only difference as far as I can tell is that our development cluster has a slightly newer set of ubuntu updates and a bit weaker hardware.
I will continue to investigate. 
Do you get the same exception as we do?

About the thread stopping I don't know since we haven't seen this in production yet. 
My guess would be that if the thread is stuck in an infinite loop somewhere inside jsf/richfaces, you cannot in a safe way terminate it from the outside.
