A little more information. We did start making some disk changes on
these servers. I was going to be moving from file based to physical disk
based VMs from our SAN. 

We added two 20gb disks at LUN1 and LUN2 and moved the 400gb disk to the
end at LUN50. I modified fstab to load the 400 gb disk at the same mount
point. 

If/when the system hangs again we'll try moving removing the 20 gb disks
and have only the 400 gb disk. Don't see how this will change anything
though. 

Thanks,
James
