Severity: 3-Major


In MRF/Diameter deployment, mirrored connections on the standby may be lost when the "process ingress error" log is observed only on the standby, and there is no matching log on the active.


Diameter mirror connections are lost on the standby. When failover occurs, these connections may need to reconnect.


This can happen when there is a large amount of mirror traffic, this includes the traffic processed by the active that requires mirroring and the high availability (HA) context synchronization such as persistence information, message state, etc.



Fix Information

Diameter mirror connection no longer lost due to "process ingress error" when there is high mirror traffic.
