cupsd: Child exited on signal 25!

[Soubeille]

Hello;

I work on Linux Redhat 3.4, cups v1.1
Cups had worked fine, but now when I start cupsd, I have an error message:

#/usr/sbin/cupsd
cupsd: Child exited on signal 25!

If I use #service cupsd start , same error.
The log files of cups are very larges, the permament error is:
Unable to get printer status (client-error-not-found)!
(because cupsd is not running probably)

Could anyboby tells me why I have this error message?
What is the problem?
Thank you.
