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
