Hi,

We're seeing this at the moment. It's quite a beefy box and we can't
see any reason why cups is running so high:

4 x Intel(R) Xeon(R) CPU E5345 @ 2.33GHz

rpm -q cups
cups-1.3.7-11.el5_4.6

rpm -q samba3
samba3-3.5.2-43.el5

Samba is from sernet and is running with an OpenLDAP backend in full
domain mode with about 100 users and about 12 printers.


top - 14:28:21 up 21:07, 5 users, load average: 1.35, 1.07, 1.13

We've switch off logging in cupsd.conf which has helped bring it down
from 99% CPU.

Anyone seen this before?

Thanks.
