[Pdns-users] strange servfail

[Aki Tuomi]

Is it possible for you to provide actual data? Also,
 - have you turned on dnssec support? gmysql-dnssec=yes
 - can you provide the actual line(s) from mysql database
 - can you run pdnssec check-zone zone

All dig commands are run from a completely unrelated server: dig a www.example.com [1] is working: it returns the right A record dig a example.com is working: it returns the right A record Now this is where things go wrong: dig a abc.example.com returns a SERVFAIL but I am expecting a NXDOMAIN response because there is no A record for abc.example.com I checked the PowerDNS logs and this is there: Oct 29 16:44:45 ns1 pdns[27687]: Exception building answer packet (Unknown DNS type 'example.example.com') sending out servfail Oct 29 16:44:45 ns1 pdns[27687]: Exception building answer packet (Unknown DNS type 'example.example.com') sending out servfail Oct 29 16:44:45 ns1 pdns[27687]: Exception building answer packet (Unknown DNS type 'example.example.com') sending out servfail Oct 29 16:44:45 ns1 pdns[27687]: Exception building answ

I have tried an online tool like http://www.kloth.net/services/dig.php [2] as well and it generates the same error in the logs but only once instead of five times. Can anyone point me in the right direction? I'm stumped. I'm running the latest version on Debian. Thanks, Martin
