[Samba] S4 Crash

[Sandbox]

Hai Guys,

I have a serious problem with my Samba 4.0.5 and it is getting often and
often.

Usualy when a user would like to renam e a file samba crashes and lock out
the user.
Nothing works just server restart and I mean the entire server not just
samba, if I restart samba..nothing happens, the user(s) could not reach
their shares.

I attached a log about the problem.

Thanks, Robert
