Symptom: It is observed that sessmgr crash appears with signature, which is as follows: Assertion failure at sess/sgsn/sgsn-app/gtp_c/gtapp_tun_fsm.c:6887 Note: Rcvd Invalid Local Event <Abort Procedure> from SM-APP for IMSI:226013550179550, NSAPI:5. Current GTP State:GGSN-INITIATED-DELETE-PENDING Function: sn_gt_process_inv_local_event() Conditions: ->Inter rat to 2g from 3g. ->Authenication done at 2G. ->In 2G while waiting for perform confirmation received SGSN-context-request from peer sgsn (old israu procedure kick starts). ->SGSN-context-response to peer and context-ack from peer (somehow, pdp-context is stuck in UPC response pending state from GGSN). DPCQ from ggsn on the same pdp-context. RAU request to 3G and handoff request to 2G from 3G - this led to sessmgr restart, while trying to feed the abort-procedure event to GTP which was waiting from DPCR from SM.
