Description (partial)

Modem stuck in online(pk) state

CM re-send REG-REQ-MP while CMTS is waiting REG-ACK from CM.
In such case, a dummy response with empty SFID and SID info append to the response queue by mistake.
So RP received 2 fragments from CLC, first one with valid SFID and SID but second one is the dummy which caused the traceback.

Also, in logs following message is seen:
%UBR10000-3-RP_INVALIDSID_ASSIGN: Invalid SID assignment for interface:
