Recovery:
An IP network or Adjacent node problem may exist preventing from transmitting messages into the network at the same pace that messages are being received from the network.
Use Main Menu > Alarms & Events to determine if the ComAgent worker thread may be experiencing a problem preventing it from processing events from User Data FIFO queue.
The mis-configuration of Adjacent Node IP routing may result in too much traffic being distributed to the MP. The ingress traffic rate of each MP can be monitored from Main Menu > Status & Control > KPIs.
Each MP in the server site should be receiving approximately the same ingress transaction per second.
There may be an insufficient number of MPs configured to handle the network traffic load. The ingress traffic rate of each MP can be monitored from Main Menu > Status & Control > KPIs.
If all MPs are in a congestion state then the offered load to the server site is exceeding its capacity.
