Hi Steve,
When I shut off everything except apache with very low load and
qpopper it is still maxed out.
Here is another look with the vm setting off.
I don't always see the idle: cpu in the list as it changes
constantly. I have a hunch this is disk related but I am not sure. I
include two snapshots below
Thanks,
Paul
