What's wrong with MariaDB 10.5

After clean install Wordops 3.13.2, MariaDB use lot of VIRT and my WP-Rocket can't Preload cache. Anyone have the same issue like me.

PhatLam Hello,
are you able to run the command mysqladmin ping ?

yes, it returns mysqld alive. But when I command wo stack status, it returns mysql is not installed. That's weird...
