    What to do if JBoss keeps going out to lunch?

    John Wiegley Newbie

      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,
