I have uploaded the log (starting 11:00 AM to 2:30 PM, it is 36 MB in size!!) to google drive and invited you all.  Request you to check and suggest. The logs are from PDC emulator. We have one more additional domain controller. If you need I can enclose the logs from second DC as well.

I know you ruled out using Samba 4.7, but I would still suggest running
the current 4.7 git tree. 

You are having repeated failures of your main AD, I think the balance
of risk is quite different in your case.  You can add an additional DC,
and see how that one goes.
