Description (partial)

Symptom:
Session manager crash

Conditions:
An Attach attempt  from a UE fails due to an Initial Context Setup Failure from the eNodeB, followed by a second Attach attempt from the same UE before the call is cleaned up.  The second Attach succeeds with the eNodeB and the UE, then before a response is received to the Modify Bearer Request, a Path Switch Request is sent from another eNodeB.  The crash would not occur if the first Attach attempt were to succeed instead, or if the Modify Bearer Request were to receive a successful response before the Path Switch Request is received.
