[jboss-user] [Installation, Configuration & DEPLOYMENT] - What to do if JBoss keeps going out to lunch?

Hello, I'm running a webapp on JBoss 4.0.5GA. It runs fine most of the time. However -- and this happens almost every day -- there comes a moment when JBoss seems to go "out to lunch". Once this happens, the following is all I ever see when trying to use my webapp: java.rmi.NoSuchObjectException: Could not activate; failed to restore state | at org.jboss.ejb.plugins.AbstractInstanceCache.get(AbstractInstanceCache.java:134) | at org.jboss.ejb.plugins.StatefulSessionInstanceInterceptor.invoke(StatefulSessionInstanceInterceptor.java:236) | at org.jboss.ejb.plugins.CallValidationInterceptor.invoke(CallValidationInterceptor.java:63) | at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor.java:121) | at org.jboss.ejb.plugins.TxInterce... This of course gives the impression of extreme instability, since the only way I've found to fix this is to undeploy everything and restart JBoss. How do I counteract this? Why is it happening? I need 100% uptime, and I'm not even really doing anything serious once this starts happening. Any ideas appreciated, John View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4065628#...
