Very high cpu usage

I noticed sometimes Virtualmin stuck in loading pages, so I tried to see the stats. It has 98% cpu usage in home and around 70% in running processes.

I only setup for one website and it’s not even running yet.

What’s wrong with Virtualmin?

There major thing that causes High CPU usage is when you are being attacked from different locations or someone is brute forcing your server. It is recommended to secure your server.
