Multiserver installation. Getting this and similar messages on different slave servers: <server-name> - 28.12.2025-07:35 - WARNING - Falsche Anfrage / Wrong QuerySQL-Query = SELECT count(server_id) as number from sys_datalog WHERE datalog_id > 5491 AND (server_id = 8 OR server_id = 0) LIMIT 0,1 -> 2006 (MySQL server has gone away) Thanks.
This means that the mysql server did not respond, so it's not a wrong query. The actual error message is "MySQL server has gone away". Reasons for this can include, for example, that MySQL was restarted or updated at the time the query was sent.
