    Last week one of our WHM servers started going crazy.

    While total memory usage is not high (about 30% or so), swap usage is 100%! Reboot does not help a lot. Swap usage goes to 0% after reboot, and memory usage is about 30% like always. After several hours CPU/memory usage is same like after reboot, but swap usage goes to 100% again.

    What's the problem?

    Had that a few years ago...

    You probably have bad RAM. I would have the data center give you new RAM.

    Ram doesn't get used.

    The system is calling for memory, if your RAM isn't responding, it will spill over to your swap for the needed memory. You probably got dud RAM. It happened to me 2-3 times. They change the RAM and everything is better.

    I'd check for out of date scripts on your server being hit or some other similar issue. CSF would probably help here in pointing out more to you via email alerts.
