Firstly, I have 2 nameserver, the first nameserver is the

I have remove zonefile from the first server and reload named process.
It can work normally, I got the SERVFAIL response when I try to query
from it.
if the server is configured to read zone file, but can not find the file, it
treats this as an error and returns SERVFAIL.
And at the second server, after it remove zone from named.conf and
`rndc reload`, it also can query from the new authoritative
nameserver.
if you don't remove the zone file, but the zone definition, the zone is not
considered as local, and recursion takes place.
But after a few hours, new TTL is 600, it go back to query
from my first server which give me below log.
some of new authoritative files contains NS record for the domain pointing
to your first server, so the recursive server asks your first server, which
returns SERVFAIL.
I must do the `rndc flushname domain.tld` to flush the cache.
However a few hours after I flush cache, the problem occur again.
Does anyone ever face this problem?
such problems appear when people put incorrect NS records to zone files.
Note that not only parent zone must have proper NS (glue) records to child
zones,
but the child zones must have them too.
