Please do not edit program or log output, it makes it impossible to help you. Please see https://blog.powerdns.com/2016/01/18/open-source-support-out-in-the-open/ for an explanation.
That said, pdnsutil reports it as an Error because it is a misconfiguration that you need to fix.

The pdnsutil error about 'No delegation for zone' is not the cause of this MySQL error. Your MySQL server disconnecting your pdns_server is the cause of this error. If your machines do not get a lot of queries, MySQL may decide to time out those connections. If that is the case, you should increase wait_timeout in your MySQL configuration to hours or perhaps even days.
