MySQL is most likely crashing due to insufficient RAM. 512MB isn’t much when you’re running both a control panel and full stack (Apache or NGINX, MySQL or MariaDB, PHP, etc).

When it comes to control panels, I normally recommend at least 1GB of RAM, though 2GB is ideal as you need RAM not only for the services you’re running, but any processes that the control panel runs, as well as for your site.
