It means what it says: some resource record had a format error. This
either means you've put syntactically incorrect data in the zone file
and the name server somehow accepted it and is generating bad data or
else something is mangling the DNS packets on the wire.

Oh and *please* use a decent lookup tool like dig. nslookup is
disgusting and irredeemably broken.
