QueueSender stuck in org.jboss.mq.il.uil2.SocketManager.inte
Hi,
I'm running jboss-3.2.5 and after running for a while my application gets stuck sending a message to the server. Looking at the stack dump shows that the wait() call on the message object in the SocketManager on line 241 never gets notified. However, both the read and write tasks are still running. I have already tried to close and reconenct the queue connection every hour, but that hasn't helped. Has anybody experienced the same problem? Any pointers are appreciated.
Exerpts from the stack dump:
