Mariadb 10.3.22 has Big Problem

Hello,

When you get a “Error establishing a database connection” error you can restart mysql stack or configure wp-config.php

I try to restart mariadb but I can’t there are some errors on systemctl status mysql:

This is a bug on Mariadb you can check iti here https://jira.mariadb.org/browse/MDEV-21826 Affected versions: 10.2.31, 10.3.22, 10.4.12

Solving is use different maridb version like 10.2.32, 10.3.23, 10.4.13

@workservices As a temporary fix you can run the following commands to restore the default my.cnf content and get the MariaDB working as usual:

cd /etc/mysql
cat my.cnf.default-pkg > my.cnf
killall -9 mysqld
service mysql restart

@nsgoyat I do appreciate given immediate assistance.
