Or you are not keeping /tmp on the same filesystem as root (*good* idea, especially if you have a NetRape installed on the system and lusers knowing about said FPOS) and regulary remove all old files from /tmp (also needed, normally done from crontab via reasonably frequent check for the amount of space remaining there).
