Hi,
I have some unbounds (well, mostly -or exclusively, haven't checked yet- the FreeBSD shipped 1.4.22) with some local (intranet) zones forwarded.
Sometimes after something happens unbound starts to give NXDOMAIN for these records. Sadly it happens very infrequently, so I don't have any verbose info on that currently. (but will collect them if I know what to do)
The zones in question are configured like that:
private-domain: domain.intra
domain-insecure: domain.intra
private-domain: domain.intra2
domain-insecure: domain.intra2
stub-zone:
name: domain.intra
stub-addr: 172.28.18.1
stub-zone:
name: domain.intra2
stub-addr: 172.28.18.1
Where 172.28.18.1 is a bind server, which gives back NS records like this:
domain.intra name server ns1.domain.intra2
domain.intra name server ns2.domain.intra
When I start unbound, the resolution works. Sometimes it works for weeks or months, then suddenly fails.
What could cause this and what should I report if I can reproduce it?
Thanks,
