I am having trouble with DNS clustering between 3 servers (2 of which are name server too), entries are getting duplicated in named.conf which of courses causes named to fail.

Funny thing... I have the same problem, but it not just duplicates one account it triples it. It only happens to one domain. Very strange.

I have 3 servers in the cluster syncing each other ns1, ns2, ns3.
Now and then, when adding a new zone, i get duplicate entries in named.conf only on the server which runs ns3....:(

How do you have them syncing?
Option 1
ns1 to ns2 and ns3
ns2 to ns1 and ns3
ns3 to ns1 and ns2

or
Option 2
ns1 to ns2
ns2 to ns1 and ns3
ns3 to ns2

I set my like option 1 above and sometimes get the duplicate problems. I was thinking about moving to option 2. It should have the same effect - IF ns2 will relay between the other 2.
