VPS uses ubuntu 20.4 LTS
no, when I found that problem. I've just installed on July 2023. The key when restart server/VPS... mariadb offline and got an error.
the solution is fresh installing, since not to shutdown or restart VPS/ server it's safe.
her it is the result
server2+ 12049 0.0 0.0 8160 720 pts/0 S+ 17:00 0:00 grep --color=auto mysql
But, 2 days ago, i rebuild my VPS because mariadb offline.
