      I'm running a soak test for EAP clustering failover. In my run overnight I see occasional exceptions when a server is killed and another one needs to take over. The application I use for testing is the simple cluterbench. WELD-831 seems to be about the same exact thing but it was closed as out of date.
      It seems hard to reproduce because it needed a couple of hours to manifest.
