bad PEM session lookup request via MPI
tmm core .
PEM is provisioned.
None
if possible, avoid the ASSERT and instead just log an error and return a bad MPI response to the requestor. OR Try to find how PEM queries the session db, and validate the session in the caller instead before sending a query or MPI call, therefore avoiding the core.
