Hi In our production system, we are sending 2 bytes 300000 messages continuesly to a topic. After sending 100.000 message, serveror client throws java.jms.IllegalStateException, "session is in closed state". So we catched this exception and re-creates session. Is this correct behaviour? Why the session has been closed by the server? Thanks; Gurkan View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4233869#...
