Subjectpage_alloc problem...
Hi,

I have had three page_alloc report errors on a machine that is running as
an email and gateway server. Max uptime last night was 10 days...

The machine is a Duron 850 running 2.4.2-2 Redhat, I have 3 other machines
runnning similar hardware, (Duron 700) one on 2.4.3 built from a tar ball
RH 6.2 and the other on RH 2.4.2-2 as well.

Can anyone help me identify if this is a hadrware fault - ie faulty
hardware or if this is a problem with the specific hw design - Soltek MB
or if this is a known issue and I need to upgrade to a recent 2.4.9 or
similar kernel?

thanks for your help

cheers
Mark
