Hi,

I have very high load on my OES2 Linux servers (part of a cluster).
Hardware is HP DL360G5 10GB memory physical install.

oes2a:/etc/init.d # procinfo
Linux 2.6.16.54-0.2.8-smp (geeko@buildhost) (gcc 4.1.2 20070115) #1 SMP Mon Jun 23 13:41:12 UTC 2008 4CPU [oes2a.]

Server is completely idle, but load is still very high, what could be causing this?

Thanks,
Frank
