In JBM 2.0.0.BETA3, if a client shuts down without closing its connections (e.g. it crashes) you see the following in the server log file: anonymous wrote : 09:37:31,347 WARNING [org.jboss.messaging.core.remoting.impl.RemotingConnectionImpl] Connection failure has been detected Did not receive ping from client. It is likely a client has exited or crashed without closing its connection, or the network between the server and client has failed. The connection will now be closed.:3 | 09:37:31,348 WARNING [org.jboss.messaging.core.server.impl.ServerSessionImpl] Client connection failed, clearing up resources for session 0687b9f5-7d74-11de-9648-0019b9ebba6b | 09:37:31,348 WARNING [org.jboss.messaging.core.server.impl.ServerSessionImpl] Cleared up resources for session 0687b9f5-7d74-11de-9648-0019b9ebba6b If possible it would be great if this message could output the IP address of the client that caused this. This would help to determine the location of a faulty client. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4247200#...
