Comment 5 for bug 1412621

I have seen this manifest as M.Morana mentioned wheen there is a DNS issue routing the master MAAS node. Another thing I have noticed is that sometime I have to set the toggle the PXE interface to "unmanaged" and then back to "DHCP and DNS" this causes DNS to start working again. I have tried using "sudo dpkg-reconfigure maas-dns", but this never seems to resolve the issue and restart bind9 correctly.
