[Server 20303.1] DNS Service crashes

I have two DCs that run DNS, with integrated AD zones. I have an AD forest built on a domain with two DCs, and a child domain. In earlier builds of Windows Server, this all works great. However, it looks like DNS now crashes pretty much any time it tries to do anything.  Every time I restart DNS, it crashes - my Application log is full of error events:

I had this issue earlier but it want away with later builds. But now it seems back.

A regression?
