You have an odd setup.

You _should_ only be doing updates on a single "master" with all of the
other servers being defined as slaves.  If you have dynamic updates
going to multiple "masters" in one zone, you may want to consider
breaking it up into multiple zones, each with one master, or looking
into "allow-update-forwarding".

Sounds like you may want to look at re-engineering at some level.
