Kernel version on the linux box?
How long is "a significant amount of time"? 1s, 30s, 10minutes, ...

smbfs doesn't do oplocks or file locking or anything, and is generally not
being a nice client when it comes to having files opened at the same time
as other clients.

Some kernel versions have been worse than others at this (esp some older
2.2 versions).


If you are using a recent kernel version, a testprogram that triggers the
failure for the windows and linux sides would be nice. It should be
possible to just disable caching in smbfs.
