This is due to the client failing to acknowledge the Oplock break
(usually).

If possible, you should use the version of Samba on the SNAP appliance. 
Samba backed by NFS is not a good idea - you probably only get away with
it due to the age of your Samba installation.

Samba 2.0.7 has known security holes, and should be upgraded to current
3.0.  

Depending on which SNAP appliance you have, you may be able to purchase
an OS upgrade (to the Linux/Samba 3.0 based version).
