Seeing this repeated pretty frequently in the Console logs for on my Macbook Pro running 10.10:

10/24/14 9:59:04.175 AM discoveryd[57]: Basic DNSResolver  Return Code is 9 and we are treating it as an error!

Any ideas why?

  • +1 I'm seeing this logged once per second on both my 10.10 machines (MacBook Air and my Mac Mini). Would love to know what's causing it! – eggyal Oct 30 '14 at 7:41
  • what does it show in your sys-pref-network-DNS ? (IP address?) – Ruskes Oct 30 '14 at 18:30
  • Do you still get this error on 10.10.2 / 14C109? – bmike Feb 11 '15 at 18:05

This seems to do the trick although not a perfect solution my any means...

Primary DNS is the local machine -- Yosemite Server Running -- Other DNS are Google, OpenDNS, ISP

DHCP on the server... all other DHCP shut-off
