> [JBoss] 01:42:41,348 ERROR [SerialSessionBean] problem removing SFSB thread
> [JBoss] javax.ejb.NoSuchEJBException: Could not find Stateful bean: ag2g4z-q52gwe-ftdr0t7i-1-ftdrio8f-2th
> [JBoss] 	at org.jboss.ejb3.cache.tree.StatefulTreeCache.remove(StatefulTreeCache.java:216)
> [JBoss] 	at org.jboss.ejb3.cache.tree.StatefulTreeCache$RemovalTimeoutTask.run(StatefulTreeCache.java:739)
> Presumably the NoSuchEJBException happens because a request thread has removed it while the removal task is looping.
> Problem is the NoSuchEJBException terminates that loop of the RemovalTimeoutTask. And an entry is left behind in the StatefulTreeCache.beans map (question: why??) that will cause the next loop of the task to try the same thing -- and fail again.  Effect is bean removal comes to a halt.
> To-dos:
> 1) RemovalTimeoutTask needs to catch errors on each remove() call and not let them prevent handling of other beans.
> 2) Need to ensure the StatefulTreeCache.beans map is cleaned up properly.
