WordPress going offline for some minutes in some database-intensive activities
I am using a WordPress droplet for this website: Trovalost.it
but when I try to do some MySQL-intensive activities (i.e editing more than a post, or fixing links in web pages) sometimes MySQL goes offline. I looked in /var/log/mysql/error.log but it looks empty, so no idea about what problem I need to solve.
Looked inside /etc/mysql/mysql.conf.d/mysqld.cnf
and it is ok for log ON.
/var/log/mysql/mysql-slow.log is empty too.
Any hint for this?
