[Samba] [4.3.11-Ubuntu] SMBD keeps Locks on NTUSER.DAT and ntuser.ini after logout

After having migrated my machines and user to Samba 4.3.11 on Ubuntu 16.04.1
(no domain upgrade, new provision, all accounts new defined) and old data
copied over to the new machines, I have now a broader testbed and notice
issues I didn't see prior to that.
Having roaming profiles (defined in the user object in LDB)...
Seemingly at random smbd keeps locks on NTUSER.DAT and ntuser.ini for a
random time (from minutes to over 2 hours).
In this time it is not possible for the user affected to login any more
(from any machine).
Error is: "The User Profile Service failed the sign-in"
The only solution is to call me and I kill then the process on the server.
Sure, this is not a prospect with pleasant ending.
On the (member) file server I see:

The Clients are mostly Windows 8.1 (they connect with SMB3_02),
a couple of Windows 7 (they connect with SMB2_10)
a couple of Windows XP (they connect with NT1)
and my linux cifs mount (NT1)
I have the gut feeling, that SMB3_02 is mostly affected (but that's also the
majority of my machines) and it comes more often, if the user does a
shutdown than simply a logout (difficult to say, I'd need more
I saw today also a Windows 7 for about 15 minutes after shutdown keeping
ntuser.ini open, but without Locked files. The user could login from another
machine without problems

fake oplocks = No
kernel oplocks = No
level2 oplocks = Yes
oplocks = Yes
reset on zero vc = Yes. (This doesn't help. Making a login with another user
on the same machine didn't break the former Lock)
The same user won't be always affected.
At the moment I think to try desperately either
- to restrict the client max protocol to lower (NT1?), or
- to set veto oplock files = /NTUSER.DAT/ntuser.ini for the Homes share
... unless someone of you knows the problem and has a probed solution.
Please, what do you think about this?
