Hi all

For some odd reason I noticed that our one cPanel VPS stopped responding, even though the load was low. I could see a few websites, but email, cPanel, WHM, SSL, etc wasn't working.

When I SSH'd into the server, the load average was about 6, dropping down to 0.08 after about two minutes, so this seemed fine.

Code:

I rebooted the server, and not long after that I noticed it doing the same.

Any suggestions?
