The new samba4 machine is running 4.0.7 and the existing is running 4.0.1. I am a little hesitant to do an in-place upgrade of the last working DC, so I wanted a replica to fall back on in case things go bad.

This is really interesting.  We are fighting with this in our automated
testing, but we assumed it was due to runtime schema changes.  Presuming
you have restarted Samba since the last schema change, this points as a
more sinister issue.  

Can you take a clone of this sever, and on an isolated network upgrade
this to git master, and try to join another git master server to it? 

If that fails in the same way, we may wish to get a dump of this object
(and potentially the database via a secure route) so we can investigate
