samba - Sep 2016 - Corrupted Files - Samba 4.4.x

Hi guys.

I´m experiencing some problems with corrupted files with samba 4.x.

I´m using samba 4.4.4 and some files like excell, word, libreoffice are
getting corrupted.

The only thing that i saw at log files is this:

[2016/09/19 13:54:00.312578,  0]
../source3/rpc_server/svcctl/srv_svcctl_nt.c:326(_svcctl_OpenServiceW)
[2016/09/19 14:06:02.591121,  0]
../source3/smbd/oplock.c:701(oplock_timeout_handler)
  *Oplock break failed for file papeldeparede.jpg -- replying anyway*
[2016/09/19 15:03:03.891095,  0]
../source3/smbd/oplock.c:134(downgrade_file_oplock)
  trying to downgrade an already-downgraded oplock!
[2016/09/19 15:03:33.908275,  0]
../source3/smbd/oplock.c:701(oplock_timeout_handler)
  *Oplock break failed for file Rede 2016/Livros/Of¡cios CMDGER 2016.docx*

My shares are like this:
[SHARE]
        path = /dados/SHARE
        browseable = Yes
        writable = Yes
        read only = No
        force create mode = 0660
        force directory mode = 0660


Can anyone help-me to solve this problem?

thanks!!

Almost certainly you have a bad network. Fix that
and the problems should go away.

Hi Jeremy.

The network should be the first option, but it is all new and certificate.
We didn´t detect any problem until now...

I will tell to my technical guys to check network again.

tks
