I am getting intermittent exceptions (stack trace to follow) on the server side
when using HA JNDI any a moderate number of multithreaded clients that have
fairly uniform request profiles from the server.
I am using JBoss 4.0.3RC1 with EJB3 RC1. Any constructive help would be
appreciated.
The stack trace is as follows:
11:40:10,326 WARN [RunnableTaskWrapper] Unhandled throwable for runnable:
