"sometimes gets stuck" is really not enough to solve your problem.
It might be that you run out of resources and the thread is waiting for them to return to the pool -- these will produce timeouts eventually though.
Thanks for your reply but i cannot explain my problem more than "It gets stuck" ,because it shows no error.JBoss just stop processing requests.
oh, youre not shutting down the server -- you're saying it gets stuck, you hit a key and then it continues... and youre on windows
keep your mouse off the console window that you're running in, or turn QuickEdit mode off.
I have exactly the same problem. Under Win 2000 Server some times jboss does not process the user request.
Do you find a solution?
turn QuickEdit mode off on your console
