1. Navigate to Alarms & Events to examine the alarm log.

   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. The Task thread may be experiencing a problem preventing it from processing events from its event queue. It is recommended to contact unresolvable-reference.htm#GUID-DD0927BD-FD0B-4CEB-86E9-98A33C12D4E0 for assistance.

2. Navigate to Status & Manage > KPIs to monitor the ingress traffic rate of each MP.

   Each MP in the server site should be receiving approximately the same ingress transaction per second.

3. If the MP ingress rate is approximately the same, there may be an insufficient number of MPs configured to handle the network traffic load.

   If all MPs are in a congestion state, then the offered load to the server site is exceeding its capacity.
