[c-nsp] IGMP on 6500s - %MCAST-xx-GC_LIMIT_EXCEEDED

[Tim Stevenson]

Phil - as Sukumar points out, this definitely refers to the standby. 
This is the bug I had in mind, hence my questions. There is not yet a 
s/w release with the fix available. In steady state, this should not 
cause issues w/forwarding traffic - there is the possibility on 
switchover however that new group MACs would not be able to be 
installed until some of the old source-only entries are aged out on 
the (new) active sup.

Thanks,
Tim
