[knot-dns-users] Re: Issue - trailing data

Hello! I have an issue. Knot is configured as a secondary server, and when receiving a zone, a "trailing data" error occurs, preventing the zone from being loaded from the primary server. ``` Jan 30 11:03:40 hostname knotd[5407]: info: [domain.com <http://domain.com>.] refresh, remote 50788646-db98-4caa-b26e-95b30a470796, address 1.2.3.4@53, failed (trailing data) ``` The same warning appears when using the `kdig` utility: ```bash kdig @1.2.3.4 <http://1.2.3.4> domain.com <http://domain.com> AXFR > /tmp/domain.com <http://domain.com> ;; WARNING: malformed reply packet (trailing data) ;; WARNING: malformed reply packet (trailing data) ``` The issue occurs specifically with large zones. If the zone requires 2 messages to be received (e.g., `Received 32720 B (2 messages, 442 records)`), one warning appears. If it requires 3 messages (e.g., `Received 49083 B (3 messages, 878 records)`), two warnings appear. However, if I place this zone (`/tmp/domain.com <http://domain.com>`) into `/var/lib/knot` and then execute: ```bash knotc reload knotc zone-refresh domain.com <http://domain.com> ``` Knot successfully loads the zone. Unfortunately, due to confidentiality, I cannot share the contents of the zone. Additionally, I do not have precise information about the software installed on the primary server. However, if BIND is used as the secondary server, there are no issues. A regular `dig` command also does not return any errors. Is there any way to make Knot ignore the "trailing data" error and successfully load the zone? Thank you for your help! --
