[CentOS] cupsd takes 100% of cpu

[Dan Halbert]

Thanks to all for the suggestions. I did do lsof on the process and saw 
nothing interesting (just libraries). Attaching gdb to the process 
showed that it appeared to be looping inside getservbyname().

However, after a little more thought, I "rm -rf"d /var/spool/cups/ 
(which had some stuff from 2007) and restarted. No more looping! Now I 
can configure my printers. We'll see whether it keeps working.
