    Description

      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 WELD-831 seems to be about the same exact thing but it was closed as out of date.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.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
