Check your configs and database, see if you have a zone "" or "."
As misconfigurations go, this isn't a very scary one. You should never
be receiving queries at this nameserver for domains that you're not
authoritative for - that is, unless someone has wrongly pointed NS
records at this server.
However it might trip you up if you point one of your *own* domains at
this server, but haven't yet added the zone, and some proportion of
queries which hit this server get an authoritative NXDOMAIN response,
which the user will see as "this site cannot be reached" or similar.
