Yes. I have setup another script last night to check output of
ifconfig every 1 second, it fails 7-8 times a day - 4 times last night
until this morning (central european time here).

I have: # rpm -qa | grep clum
clumanager-1.2.26.1-1

There is no new version on RHN, just checked with up2date(8).

I agree. That was my thinking also. We have escalated problem with
e1000 driver to HP (e1000 is part of their official support pack for
RHEL 3 on DL 380).

e1000 driver version is e1000-5.7.6a-1. From
ftp://ftp.compaq.com/pub/products/servers/supportsoftware/linux

I'm afraid that I cannot put test kernels on that machines. They are
in production and my head can get on the chuck if I do this. :-)

Which version of initscripts? I have initscripts-7.31.22.EL-2

OK. Thank you.
