DNSSEC zones not updated

Sadly, no ideas other than a shared experience. It's not just the Windows release nor is it just the 9.14 series of releases; we've been witnessing this since the 9.10 releases on Linux (whilst using inline-signing). I don't recall off the top of my head if we saw it in the 9.9 series; even for my memory that is too many iterations ago.
It isn't a regular occurrence by any means and it is fixed with a service restart. Sadly we only see this in our production environment and coupled with the time between the occurrence of the issue and the detection of the issue, getting decent debugging information has been challenging (which is why we haven't done much else about it other than restarting it when we see it occur).

Aihe: Re: DNSSEC zones not updated
And we also get after a change and a reload the "secure_serial: not exact" error, of course because the signed zone is not in sync with the non-signed anymore. So I guess the question is why it is not signing automatically after updates to zone.

Yed we have quite several times by now when trying to find the culprit. Also the whole windows 2019 server. And it is not only this domain/zone, but all of them.

Hi,
did you try stopping BIND, removing journal files and then starting BIND again?
If the signed copy of the zone got corrupted in the memory, you might be dumping the corrupted version on disk again with `rndc reload`.

The SOA & serial numbers *are* updating in the queries, but the actual records not. Example the MX records, currently I have priorities 55 and 25, still inquiries return the old 20 and 20. Same with any records, the changes does not get updated.
