TMM crashes when the route to PCRF is lost.
TMM diameter module tries to communicate, does not handle the error, and crashes. Module reboot. Traffic disrupted while tmm restarts.
-- PEM establishes connection with the diameter endpoint (Gx / Gy). -- The route to the diameter endpoint is lost (interface down / route deleted).
Mitigation: Ensure that the network interface configuration routing diameter packet is not manually brought down. No workaround for externally triggered failures.
The system now handles connections established with the diameter endpoint when the route to PCRF is lost.
