Recovery:

1. The percent utilization of the MP's Transport Writer Queue is approaching its maximum capacity. If this problem persists and the queue reaches 100% utilization, all new egress messages from the Transport will be discarded.
   This alarm should not normally occur when no other congestion alarms are asserted. This may occur for a variety of reasons:

   • An IP network or Adjacent node problem may exist preventing SCTP from transmitting messages into the network at the same pace that messages are being received form the network.
   • The SCTP Association Writer process may be experiencing a problem preventing it from processing events from its event queue. The alarm log should be examined from Main Menu > Alarms & Events.
   • If one or more MPs in a server site have failed, the traffic will be distributed amongst the remaining Mps in the server site. MP server status can be monitored from Status & Manage > Server Status.
   • The mis-configuration of Adjacent Node IP routing may result in too much traffic being distributed to the MP. 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 Status & Manage > KPI Display. If all MPs are in a congestion state then the offered load to the server site is exceeding its capacity.
2. If the alarm persists, it is recommended to contact My Oracle Support.
