I know I comes with samba 4.1.6 so I thought great, but I should have 
know better after the mess they made with version 4.1.3 in the beta release.

After Samba had been running for a short while log.samba started filling 
up with this:

When I say filling up, I really mean filling up, fortunately upgrading 
to 4.1.7 seems to have fixed it ;-)

Now it may not do this for you, but I cannot recommend samba 4.1.6 from 
the ubuntu repo.
