Description (partial)

Symptom:
Call drops may be observed when we hit this condition

Conditions:
When there are more than 11 pending PCC transactions in a sessmgr for a subscriber, Only that subscriber will be affected and dropped.

Scenario:
1)	Call falls back to Local Policy because of PCRF failure in CCR I.
2)	Call stays with Local Policy and on timer expiry we retry to PCRF.
3)	There is  a failure again to send CCR I to PCRF and call falls back to Local Policy.
4)	While the call is with Local Policy, any Modify Request received from SM is not responded to which causes SM to not process the Policy Change Request.
