We are running JBossAS 4.2.2 with JBM 1.4.4. Recently we experience a problem and I am trying to track it down. It appeared to be a network issue in that we got the following in the log: 2009-08-25 10:45:22,902 ERROR | Thread-24 | org.jboss.remoting.callback.ServerInvokerCa | llbackHandler | Error handling callback | org.jboss.remoting.CannotConnectException: Can not get connection to server.

If not, could this be the cause of the failure to get a connection? Thanks alot. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4252091#...
