Just setup Ubuntu server 12.10 and am getting a constant stream of the below:
Dec 3 20:49:33 professorx named: DNS format error from 18.104.22.168#53 resolving ./NS: non-improving referral
Dec 3 20:49:41 professorx named: success resolving './NS' (in '.'?) after disabling EDNS
I've noticed quite a few timeouts that I suspect are related. When I add edns no; to my named.conf things seem to start working much better. Thoughts?
