I noticed this happening as well when I had a heavy user load going and
suddenly someone would start pulling a two meg mp3 file through the
httpd. My fix, of course, was to nice the watchdog -19 on startup. I
don't think it's happened again since I did that.

I note that this is also what kswapd does, though it only goes to -12
(no that was not a Spinal Tap reference). I scanned the watchdog docs
and nowhere does it suggest nice'ing the watchdog process. Any reason
why I shouldn't be?
