Can anyone please assist in getting to the bottom of what appears

a nasty bug?  I'm keen to work on getting to the root cause of

Can you try reverting 3a383038ee7f74e5a9d2326a761b27950a14eb83?

nmbd does not change much, and this is one of the few changes
between
4.8 and 4.9.

I've attached such a revert (it probably won't go to list
recipients)
for your testing.

Cool.  That seems to have fixed things both in the scenario of
"domain
master = yes" set (my initial config) as well as the case of that
parameter now not explicitly defined.

In both cases Samba now starts up normally and uneventfully.

Can you please file a bug?

I think we will have to patch this pretty urgently.

No problem.
