Hello Richard,

some days ago I had heavy trouble at a customer with oplocks and smb. After
some experiments we found, that following settings do prevent corruption of
one particular file (accessed by multiple clients the same time by a DOS

 strict locking = yes
 oplocks = False
 oplock break wait time = 20
 oplock contention limit = 4

Now interestingly today I played around on a different Linux box with same
parameters that has smb AND shared cvsroot on one and same machine.

I could not checkout anything from a win box. I removed that settings on
the server and all worked again.

So locking is definitively a point.
