I hope you can help. if you can’t help, I will move to another company. meanwhile i don’t know english. from Turkey

Hello all,
This crash is most likely due to your system running out of memory. I’d suggest that you add a swap file to give yourself a bit more of a buffer. Check out this tutorial:
How To Add Swap on Ubuntu 18.04
What you can also do is to use the MySQLTuner script.
The MySQLTuner is a script written in Perl and allows you to quickly test your MySQL configuration and it gives you suggestions for adjustments to increase performance and stability.
According to the official GitHub page, it supports 300 indicators for MySQL/MariaDB/Percona Server in this last version.
To run the script you could do the following:
wget http://mysqltuner.pl/ -O mysqltuner.pl
perl mysqltuner.pl
The script would run multiple checks against your MySQL instance, all checks done by MySQLTuner are documented here.
Also as stated in the official documentation, it is still extremely important for you to fully understand each change you make to a MySQL database server. If you don’t understand portions of the script’s output, or if you don’t understand the recommendations, you should consult a knowledgeable DBA or system administrator that you trust.
As a good practice make sure to always test your changes on staging environments before implementing them on your production database.
On the same note, if you want to have worry-free MySQL hosting and focus on your application, I would recommend trying out the DigitalOcean Managed Databases:

Hope that this helps! Regards, Alex
You will need to repair your database and check for errors among a plethora of different possible causes. It’s way too long to type and explain so I will share an article here: https://mythemeshop.com/blog/fix-the-error-establishing-database-connection-in-wordpress/ for such a case. I hope the admins realise I’m not trying to spam. Just trying to be helpful.

I think you should check your code again or traffic. Database down because low of ram. Low ram because error code or high traffic.
