Recovery:

  1. Examine whether DM-IWF resources are exhausted.

    • Alarms and Events from the Alarms & Events screen (Alarm 33005 - DM-IWF PTR Pool Utilization. Refer to the DSR Alarms and KPIs Reference for details about this alarm).
    • Measurement EvDmiwfPtrPoolExceeded

  2. If DM-IWF resources are exhausted, evaluate the cause of resource exhaustion and take corrective action. Examine the following additional information to assist with determination of the cause of resource exhaustion

    • Alarms and Events from the Alarms & Events screen
    • The rate of messages being processed by DM-IWF from the Status & Manage > KPIs page

  3. Examine whether the MAP routed service is congested, by reviewing the "MDIWFSvc" Routed Service Provider's states for via Main menu > Communication Agent > Maintenance > Routed Services Status screen. If the routed service is congested

    The number of SS7-MPs that act as providers for the MAP Routed Service might be insufficient to service the offered ingress load. Individual service provider status can be monitored from Main Menu > Communication Agent > Maintenance > Routed Services Status
