Description (partial)

Path failure is detected in the scenario mentioned in the summary. But MME is not sending detach request for  UE1, which is incorrect.

This issue is seen when path failure is detected during an ongoing second Attach for a diff UE2.

1)  Do an Attach for UE1
2)  S1 HO with IDFT initiated and proceeded till Modify Bearer Req. No resp from SGW.
3)  Now do an attach for diff UE2 and in CS resp, send a diff recovery value from SGW. Make sure Path failure is detected."
4) Once Path failure is detected for SGW, MME sent Attach accept for UE2, and UE context release to eNodeB  
 and detach request is not sending  for UE1, which is correct.
