 This behaviour can be overridden by using query-source to lock down the

+Q: I get error messages like "multiple RRs of singleton type" and
+"CNAME and other data" when transfering a zone.  What does this mean?
+
+A: These indicate a malformed master zone.  You can identify the
+exact records involved by transfering the zone using dig then
+running named-checkzone on it.
+
+       e.g.
+               dig axfr example.com @master-server > tmp
+               named-checkzone example.com tmp
