Using PowerDNS, we got into an issue with transferring a single domain object (/24) from our primary to our secondary DNS server.
This /24 is part of a larger RIPE block, /22, and is not automatically transferred. The remaining /24 domain objects transfer just fine.
As you can see from below emitted output, the axfr transfer from ns0 to ns1 stops halfway.

A tcpdump on ns0 doesn't show much that helps troubleshooting?
