[Pdns-users] Timeout error: Error from remote in receive(): Resource temporarily unavailable

Thank you Peter!

We are using pdns notify to send to our DNS cluster. The IPs of these DNS
servers are already in "also-notify".

Is there still a need to resolve NS records when sending these zone notifies
to our DNS cluster? If not, is there a way to disable it?

Warmest Regards,
Jackson Yap

Without resolving the NS records, PowerDNS does not know where to send the
NOTIFYs, and thus cannot send them.

However, it's not great that pdns_control is waiting for this, because, as
you have seen, this can take quite some time. You could file a request at
https://github.com/PowerDNS/pdns/issues/new/choose to make the behaviour
smarter - perhaps delaying the resolving until after pdns_control has
returned? I don't know yet.

I doubt you own xxx.com. Please do not edit log messages, at all, when
asking for help here. To understand why, please see
