We have a Linux (Ubuntu) based server and host some smaller websites based on wordpress. Since a few days we got the error message that there is an error with the database connection. This error occures on all the websites randomly and after a refresh the error is gone.
Its also that this error occures on plesk.
Do you have any ideas why a server is loosing randomly the connection to the database?
Thanks in advance
We allready reseted the server with an backup but the error is still tehre.
