Hello,

We have Knot 1.4.6 on CentOS installation.

When doing NAPTR ddns update, like this:

nsupdate

> server x.x.x.x

> update add 3.1.1.1.1.1.1.1.1.2.7.9.9.our.domain.com. 172800 NAPTR 1 1 "u" "E2U+sip" "!^.*$!sip:123@freeswitch.org!" .

> send

; Communication with server failed: timed out

It fails with:

knotd: libknot/rrset.c:1703: rrset_serialize: Assertion `size_one == rr_size' failed.

Aborted

No issues with ddns updates with TXT records.
