Hi Vidhya,
Sorry for the delay. Are you still having this problem?
Can you see in the log which thread is holding the lock at <0x1990f6eb>? Note that the lock exists in the JBossMessaging code. While it is possible that there is some relevent interaction between Remoting and JBossMessaging, it's more likely that the issue is confined to JBossMessaging.
Have you posted the question to the JBossMessaging user forum?
