Symptom: Sessmgr reload was observed when deletion due to DBR was in progress and SGW Relocation(DSREQ with SI=1) is received. Conditions: This issue can be reproduced with below steps: 1. Create a multipdn pure s call. 2. Perform deletion of one pdn. 3. Hold the DBRSP from MME and perform SGW HO(DSREQ with SI=1). 4. Now as a result of this we were purging the last pdn for which we have to sent the DSRSP for DSREQ(SI=1). 5. Now when we receive ST conformation for all pen's and try to send DSRSP, we see the reported crash as egtpc ingress side cleanup was already done.
