Ram Leak Problem: Ram usage is constantly over 80%

I have also installed untouched Cyberpanel on centos 7 many times.
I have done a zero Cyberpanel installation on all versions of ubuntu.
But the result did not change.
I only have 1 or 2 websites on my server. While there is no problem when the server is running for the first time, after a certain period of time, the ram usage rises to over 80% by itself. (And my disk usage is increasing day by day, I don’t understand why.)
I have been using Cyberpanel for many years, but now I am feeling nauseous.
Please help me.

My Server Specs:
Ryzen 9 3950x 4 core, 4 GB Ram, 30 GB NVME SSD

System: Ubuntu 20.04.3 LTS
Codename: focal

@usmannasir

Why do you have so many MySQL processes? what are you running there?

@usmannasir I did not do anything.
I installed the official Cyberpanel on the newly installed server.
This is the result I am experiencing.
I don’t know why there are so many Mysql processes.
I am also looking for a solution.
There is only 1 website on Cyberpanel.
