Oh, this is your application then, not an extrnal one ?

Remember, Windows does an implicit read-lock check
on every read from a file, and and implicit write
lock check on every write - so you get these locks
merely by doing read and write (a Windows server
does the same).

If you want to disable this set:

strict locking = no

(by default it is auto). See the man page
for details.
