Hello! I have a some basic websites, on a VPS with Hestia Panel installed (PHP, MySQL, PHP-FPM, Apache). I am using the default plan package.
From time to time the websites (which are simple - a few simple database queries) are loading slow and MySQL stops the execution of the PHP file, showing: “MySQL Server has gone away.” error. In the rest of time, the websites are loading almost instantly.
What could be the problem? This looks like a timeout on MySQL which stops the execution. That would not be a problem for me if there is a timeout. But how to identify the reason why the php scripts are loading slow? Could it be a problem regarding PHP-FPM? What should I do?
I am new on Hestia. Untill now, I used to manually configure and install the server, but now I need a panel to make use of more features.
Thank you very much!
