Symptom: sessmgr crash: Crash occurs while sending CSRsp. Conditions: This crash may happen for a multi-pdn call at PGW. PDN-1 established. CSReq / CSRsp successful. PDN-1 has 4G-3G-4G handoff. 4G-3G handoff successful. During 3G-4G handoff of PDN-1, PDN-2 is getting established. However, due to network delay, CSReq for PDN-2 reaches PGW before handoff MBReq for PDN-1. There is a delay (48 sec in this case) on Gy side due to which CSRsp for PDN-2 is delayed. In the meanwhile, 3G-4G handoff of PDN-1 completes. Crash occurs when response comes from Gy for PDN-1 and CSRsp is to be sent.
