I downloaded jboss-remoting SP11 from http://repository.jboss.com/jboss/remoting/2.2.2.SP11-brew/lib/ and made changes suggested by Howard. We had given an idle time of 14 hours for our listener. Now some of the messages sent to the JBM queue are getting stuck as the listener is not able to pick up the message.I am seeing the following exception in the JBoss server log for those failed message deliveries. We are using JMS based listener,please help. We never had this problem when we used JBM without clustering.
