I'm also seeing similar log messages, and I'm running 12.0(14.6)S1
on this particular box, so it should have the fix for the above
mentioned bug-ID.

Here's a few of my recent messages:

006606: Feb  5 21:29:56: %PIM-6-SA_ENCAP_INVALID: Bad SA from RP 141.142.12.1

6278196C FFFF 0

It would seem that the first two are SAs for non-multicast groups(!).

The last one seems to be the multicast beacon group; perhaps no
wonder we're having trouble receiving sources there...

Is there anyone else here with a bit more clue about what is
actually causing these events?
