acpid log file filling /var partition

[David Eisner]

I'm running FC2 with the 2.6.9-1.6_FC2 kernel.  After either the most
recent kernel upgrade or the previous one (I think it was the previous
one), I started coming home from work and finding that the /var
partition on my Inspiron 5000e was full.  I traced it down to
/var/log/acpid, which was huge.  It was full of line after line of
this:

[Thu Dec  2 22:15:32 2004] completed event "button/lid LID 00000080 000002dc"

I'd have to  /dev/null >  the file before I could do anything else.

You should know that when I close my laptop lid, the machine keeps
running (no suspend).  The backlight turns off, though.  This is how I
want it (at some point in the distant past with some version of RHL,
it would suspend, and then that stopped working, but I decided I liked
it).

If I tail -f /var/log/acpid and press the little lid-close detection
nubbin, I can watch the file grow like crazy.  Once I let go, it
stops.  It's as if the nubbin were set to autorepeat.

Did something change about the recent kernels that's causing this
event to be repeatedly triggered?  Is there an easy way to fix this,
other than not closing my laptop?  Thanks!
