I had a few requests to see if this worked. We had this error message each
morning as the multicast sources came up:

But after raising the limit with the command below we no longer receive the
error.

And yes, I'm aware the N3k is brand new, hence the lack of results in Google
searches. I'll be sending through our diffs for nxrancid shortly too.
