        Please read the FAQ.

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
