I wonder if nobody else seems to have this problem.
I can reproduce this every time here, even after updating to Samba 4.1.5

Steps to reproduce are:

1. Install Samba 4 as Active Directory Domain Controller
2. Create a share (call it "Programs" for example)
3. Join the domain with a Windows 7 client and install some programs to 
the "Programs" share
4. Open some of these programs on the Windows 7 client computer
-> smbstatus on the Samba server should now show many open files for 
these programs
5. Leave the programs open on the Windows client and wait around 9 till 
10 hours
6. After 9 till 10 hours run smbstatus again on the Samba server and it 
shows no open files anymore
and all the open programs on the Windows client should not work or crash 
now when you click on a menu item
in it or something like that.

Can anybody confirm this?
