Before you start strongly disagreeing with a person who tried to help you, why don’t you start by giving us the whole picture? The configuration (named-checkconf -px), the logs (start with the lines just after the start and before named prints “running” and then the logs around the event), and a reliable way how to reproduce this. You gave us your diagnosis, but omitted all the indices that led to it. You might be right, but it is hard to very your claims without all the evidence.
