S4: Winbind and high CPU load averages.

So, this morning my load averages were running around 2.5 - 3.0,
not terribly high, but higher than normal. So naturally the first thing I
did (and no this isnt' always the case) was to make sure that I had the
latest and greatest git, after a rebuild and restart of samba I was still
seeing 2.5 - 3.0 averages. There was one process in particular causing the
issue and netstat -anp | grep pid showed several msg'ing pipes and some
winbind pipes. Just testing I took the winbind entries out of my
nsswitch.conf and my load averages started dropping. I am now down to .35
and everything is back to its normal smoothness. I guess the question now
is, why is winbind eating up all of my CPU? Any ideas/suggestions/solutions
welcome.

Thanks,
Ricky
