I don't know what kind of programm you're running, but I had nearly the 
problem. I solved it by turning of the oplocks for this share.

Try in the share:

	comment = C On Doveserver
	path = /mnt/samba
	public = yes
	writable = yes
	create mask = 0775
	inherit permissions = yes
        oplocks = No
        level2 oplocks = No
