-
This alarm indicates a routed service is load-balancing traffic across all connections in a connection group, but all of the connections are experiencing congestion. Messages may be discarded due to congestion. Congestion generally occurs when the far-end servers are overloaded.
Overload can be due to following:
- TCP connection has higher latency or error rate, then connection is getting into congestion state
- Far end server is receiving traffic at higher rate (may be from other servers). This triggers ComAgent congestion on far-end side.
- Application process CPU on far-end is above normal.
