Is that expected behavior?

Yes.  What if the first server stops getting updates, but the second one
does and has a higher serial number?  Don't you want the slaves to check
the SOA record on it to pick up these changes?

Except that the 2 "masters" are simply different interfaces on the same master ... so the serial number *better* always be the same!

Looking at the logs, it appears that the choice of masters is a second-to-second thing because what I'm seeing is that one zone goes via one interface and then the next zone, perhaps only a few 10s of ms later, goes via the other interface.

I would have expected that it would only ask the second-listed master if the first didn't answer ... but I didn't write the code (and haven't read it either!
