Description (partial)


Unused multicast flows, i.e. flows that have no member CMs in the system can take a long time to be
cleaned up and the IGMP Input process continues to hold large amount of memory.


This occurs when 
a. There are CMs that have joined multiple multicast flows
b. These CMs are not responding to any IGMP queries for the flow, ie. the are no longer interested
in receiving the flow, but have not sent IGMP leave for these flows.
