Upgraded to 4.1.5 today but the problem persists. Tried to downgrade to 
4.1.3 but no change to the issue. Now I'm unsure how long the problem 
actually existed, can be customers just did not report it in time.

Checked on the client:

Index Service is disbaled.
Oplocks are disabled.HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet 
\Services\LanmanServer\Parameters EnableOplocks=0 (Also tried it with an 
value of 1, just in case)

Tested on the samba server, disable oplocks, l2 oplocks and kernel 
oplocks. Also disabled dead time, socket, reset on zero vc and aio 
settings. Nothing fixed the issue.

This is the smb.conf i usually use since two month.

         workgroup = DOMAIN
         realm = domain.local
