Thank you so much, it works for me!
I had previously found such a message (
https://lists.nic.cz/hyperkitty/list/knot-dns-users@lists.nic.cz/thread/T3N…
), but I thought the option was related to the MS server, not Knot.
And now I understand - it's my mistake.

Hi,
Could you try enabling

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>gt;.] 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!
