That's certainly disconcerting (and diverges from the behavior we continue to see with BIND 9.3). Is there any reason these updates would work without issue immediately after a restart but stop working at some point later? As you can see in the logs I provided in my initial post (relevant lines copied below) it does work as I described after a restart, for an as-yet-determined amount of time:
