I have looked at the mydns backend and spotted at least one potential
problem that would pop up if there are duplicate record in the soa
table (duplicate with respect to the "origin" column).

Can you check if that's the case? A query like

SELECT origin, COUNT(*) FROM soa-table GROUP by origin HAVING COUNT(*) > 1

should do it (untested).

That said, the mydns backend code contains warning to not use it for
anything more than very simple setups. So moving away from it to a
proper backend should be done.
