Server stop a few times a day

[alfredo balegno]

Hi all, I have a problem with a MySql server on a DigitalOcean dopplet, which is supposed to be configured if you choose the default for Wordpress.

In the error log I see this every time the server stops:

In this case, I have installed the version:

mysql Ver 8.0.27 for Linux on x86_64 (MySQL Community Server - GPL)

I would be eternally grateful for any help.
