Bug Description
Binary package hint: cupsys
After updating the following packages:
cupsys (1.2.2-0ubuntu4) to 1.2.3-0ubuntu1
cupsys-bsd (1.2.2-0ubuntu4) to 1.2.3-0ubuntu1
cupsys-client (1.2.2-0ubuntu4) to 1.2.3-0ubuntu1
cupsys-common (1.2.2-0ubuntu4) to 1.2.3-0ubuntu1
cupsd uses a great deal of CPU resources as soon as the service is started and does not release them unless it it killed manually.

Can you post the following files:
/etc/cups/ cupsd.conf printers. conf client. conf
/etc/cups/
/etc/cups/
/etc/cups/ppd/*.ppd
Which printer model do you have and how it is connected?
What does happen if you use the "lpstat" command:
lpstat -p
lpstat -d
lpstat -v
Does it hang and needs to be killed with Ctrl + C?
Can you set "LogLevel debug" in /etc/cups/ cupsd.conf, restart CUPS (/etc/init.d/cupsys restart), and then try "lpstat" and printing commands again? Observe "tail -f /var/log/ cups/error_ log" in a second console window while doing your tests. Does it go into an infinite loop.
I have also observed this problem with an HP DeskJet 3740, set up with HPLIP/HPIJS and set as the default printer. I observe CUPS going into an infinite loop when running any "lpstat" command.
The bug seems to be an upstream problem, as it was also reported to Mandriva:

No one reported it directly upstream though.
