Package: cupsys
Version: 1.1.23-10
Severity: important

I upgraded a Woody system to Sarge recently. This is a dual-cpu (AMD
Athlon MP), if it matters.
I read the other similar bug reports, but they are not like mine.
Now CUPS constantly eats 15-20% CPU, even when not doing anything.
Setting browsing to on or off does not change anything (while I intend
to use browsing in the end).
There are around 30 CUPS clients (Debian Sarge) using it, but not printing
all the time.

I attached strace to the "cupsd" process, and here is what I get:
aldebaran:/etc/netatalk# strace -p 7756 -c
Process 7756 attached - interrupt to quit
Process 7756 detached

As you can see, there are a lot of calls to syscall "time", while on
anotheri Debian Sarge PC, there is no such behaviour noticeable.

thanks

Now we uploaded CUPS 1.2.1 to unstable.
fixed-in-experimental bugs can be closed.

About #349341, I noticed I needed to modify the order of control file.
It's already fixed and will provide a correct dependency.

Thanks,
