[CentOS] cupsd takes 100% of cpu

I have never been able to get cups to work properly since CentOS 4.x (and am now on 5.2).

When I try to "service start cups", cupsd immediately starts taking 100% of the cpu. Attaching strace to it shows no system calls happening. I have tried uninstalling and reinstalling cups to get fresh config files. My printers.conf is empty.

This is on a completely updated x86_64 CentOS 5.2 desktop system running gnome. There are no local printers attached the the box. We have a couple of networked HP printers and a Canon. I have not added any of these printers to the configuration. A lot of Googling has not turned up any help. Have you seen this problem? Any suggestions?

Thanks much, Dan
