Sessmgr reload is seen while processing the Create Session Request at Cisco SGW received from MME for Wifi to LTE Handover.

1. Long FQDN string configured in the PGW-Service which is associated with the SAEGW-Service
2. Pure-P Call established with Wifi
3. Handover CSReq received at SGW with hi=1 from MME which would convert the Pure-P call to Collapsed call [S+P].
