[c-nsp] Log messages saying %MCAST-SP-3-QUERY_INT_MISMATCH

[Phil Mayers]

A couple of our 6500/sup720 are logging:

%MCAST-SP-3-QUERY_INT_MISMATCH: Snooping Querier received a non-matching 
query interval (125000 msec)

...quite frequently. This is annoying, because it fills the logs and 
(curse you cisco!) it doesn't say from whom it "received" a non-matching 
blah, or even what interface.

This is a really busy box, so a debug or packet capture isn't a great 
way to find the cause. Any suggestions? And I'd be grateful if those of 
you about to say "just ignore it" could assume I'm aware of that option 
and move on ;o)

I've already tried examining the output of "sh ip igmp int", and 
everything appears at the defaults of 60 seconds, so I don't think it is 
showing up there.

Cheers,
Phil
