Thread Zoombie

Hi, I am having the same problem with Jboss 4.0.1, the msg is sent to the Queue, the msg is executed, but It create some kind of thread zombies even if the msg is processed with success.

And the threads never desapear until we reboot the server.

What should I do?

The same problem of this post.

But I don´t know where to configure JBoss to solve it.

Thanks.

Can you be less specific?

If you are seeing threads still allocated after 60 seconds in the server and you are using a
stateful connection like UIL2, the problem is almost certainly that you are not
closing the connection.
The threadpool tidyup has been expedited in 4.0.2 so they don't hang around for upto 60
seconds after the connection is closed.

There are many reasons why you might get a OutOfMemoryError. Whats the scenario in which you get this error? Are you sure its because of infinite thread generation? Have a look at:

See if it helps
