As I said, Samba is just responding to a request to add a SOA record to
a zone, but the request isn't in the correct format. 

If your problem isn't being caused by a bug, you need to find what is
sending the request, stop it from sending the request if it isn't for
an AD dns zone, or fix it to send the correct format it is for an AD
zone.

Now, as you say it has stopped on your new DC (note it isn't a primary
DC, all DCs are equal except for the FSMO roles and they can be on any
DC), so it may be a bug. Your new DC may be running a newer version of
Samba or its version of Samba may have been patched to fix a bug, so
have you tried updating one of the other DCs ?
