[knot-resolver-users] Re: SERVFAIL with Internal Resolver

Hi, could it be, that servers to which you forward queries are not authoritative only? Maybe they are forwarding queries to some other servers, or there is recursion enabled on them? When I was migrating from kres5 to kres6 I did also run into troubles with complicated historical DNS setup where some subzones were forwarded to other targets. I ended up with setting authoritative: false which solved the issue for me. But not sure if you have similar problems.
