- Cisco ASR 5000 Series
Known Affected Releases
Symptom: 1. 2g old inter sgsn rau procedure for subscriber-1 till sgsn context response to peer and waiting from sgsn-context-ack. 2. Subscriber-1 got freed for some reason and gtp-mm-node was not cleaned up. (could be clear subs issued on him or ms init detach or cancel loc) 3. The same smid got allocated to subscriber-2 when he entered into sgsn with new inter sgsn rau in 2g. 4. Authentication is in progress for subscriber-2 and during that time the sgsn-context-ack for subscriber-1 was received on the dangling tunnel which zeroed the teid in the smid. (but to the gmm-app this is an invalid event and does nothing) 5. After check imei procedure of subscriber-2 gmm found that the teid is zeroed and sessmgr crashed. Conditions: Same app structures should be re-allocated to a different subscriber coming via inter sgsn rau procedure after the partial clean up of the old israu subscriber.
