If there are no requests within 60 secs, the connection gets terminated by the mysql libray. The backend does notice this as soon as it tries to send a query because this fails (the connection is closed). PowerDNS then tries to reinstanciate the backend but the current DNS request will return a termorary failure. > Because I have raised the timeout to 1 day, the timeout now never occurs, > but this is a strang state for this connecties. Or not? I think the connection should never timeout at all because PowerDNS depends on the estabished connections to the database server.
