Hi,

The error indicates all connection slots to the database service have been used up. By default, that is 200 connections and 150 per any single database user.

If
Bash:
plesk db
fails then you need to restart MariaDB
Bash:
systemctl restart mariadb
 
Don't think so. The stored databases don't influence the number of connections.

Your service might be stopped, or several users use up all the connection slots.
