MESSAGE DRIVEN BEAN STOPS WORKING

[rishi321]

when the server starts up I can see it checking for messages, but for some times it doesn't try to grab messages any more. I haven't monitored it that closely to know the exact timing, but I know it's not even trying to check because I have it in debug mode and I don't see the message commands being executed at all and also messages are queued not grab by message driven.

here is my ejb-jar.xml
