Dear ISPConfig v3 Experts, I have found many these lines in Mariadb error log /var/lib/mysql/myexamplehost.err. Do they hurt? How do I correct them? My system is Ubuntu 20.04, ISPConfig v3.2.11 installed by autoinstaller. Code: [Warning] Aborted connection to db: 'dbispconfig' user: 'ispconfig' host: 'localhost' (Got timeout reading communication packets)
That's fine and nothing to worry about. This is not from ISPConfig but from other services of your system that use MariaDB as weel, especially postfix. Postfix reconnects in case mariaDB closed the connection on its own.
Hmmm so that's what it is? Since they're so regular, I thought it was the watchdog poking at MariaDB to make sure it's still up and running — and not really requiring to log in, just checking that the port/socket is open and accepting new connections.
