As the topic states the server disconnects about once an hour with invalid sql popup in the teaspeak client. Looking at the logs I see the following:
[CRITICAL] GLOBL | Dummy sql connection test faild! (Failed to execute command "SHOW TABLES". Error message: sql: SHOW TABLES returned -> -1/failed to prepare statement: Lost connection to MySQL server during query) [CRITICAL] GLOBL | Stopping instance!
