Hi Ingeborg, please see release notes:
https://downloads.isc.org/isc/bind9/9.16.3/RELEASE-NOTES-bind-9.16.3.html This is listed in Known Issues for BIND 9.16.1: > • UDP network ports used for listening can no longer simultaneously be > used for sending traffic. An example configuration which triggers this issue > would be one which uses the same address:port pair for listen-on(-v6) > statements as for notify-source(-v6) or transfer-source(-v6). While this > issue affects all operating systems, it only triggers log messages (e.g. > "unable to create dispatch for reserved port") on some of them. There are > currently no plans to make such a combination of settings work again.
