Same thing on my VPS

I recently signed up for a VPS with CentOS and CPanel/WHM. The exact same thing is happening on mine. Spikes every hour, on the hour. They last about 4 minutes and during that time there is piss poor system performance.

High IO Wait time. Memory levels are fine. No RAM swapping.

I monitored top during these spikes and the process that kept floating to the top was: md5sum

By the way, how do we fix what is going on? I am running "ps -ejH" but not sure what to look for. It is neat looking at the process tree! Sweet command.
