Hi!
root@cc-tld-sbg1:/var/log/tld-acct-by-customer# dpkg -l|grep bind9
ii bind9 1:9.18.6-1+ubuntu22.04.1+isc+1
amd64Internet Domain Name Server
Please help me debugging this issue: We have a TLD zone with ~3mio delegations
and updates every few seconds in such a setup:
customer --> incoming-bind --> distribution-bind --> public facing secondaries
Once a day, the distribution server stops sending NOTIFYs for some minutes (the
incoming is working fine), while still processing incoming NOTIFY and fetching
the zones. See logs below.
I could not spot other uncommon log messages. This bind instance also XFRs
other TLD zones in and out. While bind stop sending NOTIFYs for this zone, it
still processes other zones (NOTIFY+XFR in and out).
Do you have any hints to debug this issue? Is there some rate liming in Bind?
Frankly this is every day around 730-830 UTC. So my first guess was something
that happens once a day to one of the hosted zones, but I could not spot
something suspicious.
Thanks
Klaus
