ipfw output cannot be redirected when run in crontab (!)

I am having a very bizarre problem.
I have a script that does this:
ipfw show >> /some/file
Easy. I run this as root to test it, and it works. Every time I run it,
the previous iteration of it overwrites /some/file with the new `ipfw
show`.
But when I put that command in a script and run it out of cron, not only
does the output not get redirected into the file, but further, nothing
gets sent to the file.
I can even do things like this:
echo $date >> /some/file
ipfw show >> /some/file
echo $date /some/file
and put that script in cron - if i watch the file, it gets updated every
time with the new dates, but there is nothing between them - the ipfw show
output is just not getting there (!)
I thought maybe it was a problem with the ipfw show output, but it works
when I run it myself, so the script is sane ...
Is there some reason that you can't run `ipfw show` inside of cron ?
Thanks!
