appliation server sun appserver 8.1 jvm - java 1.5.0.11

we have jms receiver processing messages deployed in sun application server 9.x after processing 50 odd messages appserver hangs. upon restart 50 odd messages gets processed , hangs again.

no exceptions / error thrown (we modified code catch throwable , log in severe mode). hence bhavior cannot attributed code or messages re-processed.

the thread blocked impossible analyze without context.

consider attaching jvisualvm investigate better. can detect deadlock.
