J2EE nodes restart due to missed broadcast

620 Views

We have 3 XI application instances with one j2ee server node on each instance. Two are on same server (say server A), one on a different server (say server B) and we have SCS, DB etc on a third server (say C).

We have an issue with J2EE nodes restarting occasionally due to missed message broadcast.

[Framework -> criticalShutdown] Missed broadcast due to network problems. Restart is required (advanced Reconnect)

Reason is: Missed broadcast due to network problems. Restart is required (advanced Reconnect)
[Framework -> criticalShutdown] Exiting Listener Loop. This requires a restart of the node. Possible reason is an interrupted reconnect session to the message server.

We have checked with network team, there is no network problem. The load is normal and there are no abnormally large XI messages processed. Can anyone help us in fixing the problem from reoccurring.
