What's the filesystem format underneath? We've seen some issues recently
with NFS performance if the PHP include path is in the wrong order which
drove the load up to over 200 on a 24-core server with 16G RAM.

We also saw some issues with the maximum memory limits set
in /etc/sysctl.conf which created "false" load in a similar range on the
same box.

HTH,
