[knot-dns-users] Serial of secondary zones changed

Since upgrade to knot 3.6, when I restart the knot server, a new serial is generated for the secondary zones, putting them out of sync with the primary. Logs in 3.5 Aug 25 10:31:50 ns knot[45038]: info: [domain.] zone will be loaded Aug 25 10:31:51 ns knot[45038]: info: [domain.] zone loaded from journal, serial 2026023115 Aug 25 10:31:51 ns knot[45038]: info: [domain.] zone file loaded, serial updated 2026023115 -> 2026082500 Aug 25 10:31:51 ns knot[45038]: info: [domain.] loaded, serial none -> 2026082500 -> 2026023115, 21088 bytes, expires in 2137390 seconds Last line show the serial is set back to the serial of the journal loaded zone When starting 3.6 Sep 24 07:49:14 ns knot[23114]: info: [domain.] zone will be loaded Sep 24 07:49:14 ns knot[23114]: info: [domain.] zone loaded from journal, serial 2026023175 Sep 24 07:49:14 ns knot[23114]: info: [domain.] zone file loaded, serial updated 2026023175 -> 2026092400 Sep 24 07:49:14 ns knot[23114]: info: [domain.] loaded, serial none -> 2026092400, 21088 bytes, expires in 2158298 seconds The serial is not set back to the serail from the journal. As you can see in this case the primary does not use a date based serial number, thus the secondary is then out of sync and refuses the notifications -- Erwan David
