You probably shouldn't use zone transfers for such a large file even if
BIND had no problems with it. Even if you have a lot of changes, I'm
sure there isn't more than a small percentage of the total zone that
needs to be transferred each time. I'd look into using rsync or some
similar mechanism (replication of the database backend perhaps) to sync
only the changes, and save all kinds of time and bandwidth.
