[Samba] samba_dnsupdate: could not talk to any default name server

[David Keegel]

Every 10 minutes, my samba 4.0.9 (active directory domain controller)
is logging messages like these :-

2014-01-07T14:26:09.896260+11:00 gumbo samba[5198]: /usr/sbin/samba_dnsupdate: ; Communication with 127.0.1.1#53 failed: operation canceled
2014-01-07T14:26:09.896281+11:00 gumbo samba[5198]: /usr/sbin/samba_dnsupdate: could not talk to any default name server
2014-01-07T14:26:09.917096+11:00 gumbo samba[5198]: /usr/sbin/samba_dnsupdate: ; Communication with 127.0.1.1#53 failed: operation canceled
2014-01-07T14:26:09.917119+11:00 gumbo samba[5198]: /usr/sbin/samba_dnsupdate: could not talk to any default name server
2014-01-07T14:26:09.940917+11:00 gumbo samba[5198]: /usr/sbin/samba_dnsupdate: ; Communication with 127.0.1.1#53 failed: operation canceled
2014-01-07T14:26:09.940953+11:00 gumbo samba[5198]: /usr/sbin/samba_dnsupdate: could not talk to any default name server

Why is samba_dnsupdate trying to connect to 127.0.1.1 in particular?

I think that 127.0.1.1 IP address must have come from /etc/hosts :-

$ hostname
gumbo.$domain
$ grep gumbo /etc/hosts
127.0.1.1       gumbo.$domain
$

I don't have 127.0.1.1 in /etc/resolv.conf or /etc/samba/smb.conf.
