Perhaps you could run iotop find out if there is a process chewing up your hard disks. You aren't just limited to top, you can also use vmstat and iostat in this situation.

Nice process tree, what generated it?
# up2date --whatprovides iostat # up2date --whatprovides iotop
Try 'yum provides iostat'
Where do I get iostat / iotop?
They're in the sysstat package
Starting sendmail back up puts me in the high 1's to low 2's
I would think about isolating email then, especially if it's handling it unfiltered from the Internet.
