[Pdns-users] Warning in syslog after upgrade to PowerDNS Authoritative Server 4.7

[Sander Smeenk]

Quoting Giorgio Lardone via Pdns-users (pdns-users at mailman.powerdns.com):

> "pdns_server[7658]: Unable to retrieve SOA for domainname.tld, this

Hmmmm. Interesting.

I have noticed this specific 'issue' too after i upgraded to
4.8.0~alpha0+master.4.g90d8b86d0-1pdns.focal back in august 2022.
Then suddenly a lot of zones i'm secondary for started to log this at
random moments.

I came from 4.7.0~alpha1+master.826.g9c9e6a1dc-1pdns.focal at that time, and had no issues there. 

On IRC i wrote "am pretty sure the issue was introduced between 4.7~826
and 4.7~856. I am now back at 4.7~826 and no longer have the timeouts."

I stopped 'living on the edge' some time after that and switched back to
the stable branch, so i'm running pdns-recursor 4.7.4-1pdns.focal for a
while now. The 'Unable to retieve SOA' issue doesn't show in my logs of
last week.

I'll try 4.8.x stable. See if it returns.

-Sndr.
