Symptoms

tmm cores due to 'valid pcb' assertion.

Impact

Traffic disrupted while tmm restarts.

Conditions

This can happen when the Diameter filter: - Receives and queues HUDCTL_SHUTDOWN event. - Receives a HUDCTL_ABORT event before HUDCTL_SHUTDOWN has been unqueued.

Workaround

None

Fix Information

Diameter filter will now queue HUDCTL_ABORT events to prevent leapfrogging previously queued events.
