Description (partial)

A Session manager crash is observed at function sgsn_insert_into_db_list_with_ptmsi, on VPC-DI hardware.

When allocating a new PTMSI on VPC-DI hardware, if the subscriber ID that gets generated is above 0x3fff (16k), the one bit is truncated while stuffing the subscriber ID in PTMSI. Also, this PTMSI may conflict with existing PTMSIs. This results in a crash during PTMSI processing.
