samba - Sep 2002 - 2.2.5, MSAccess XP Database files (mdb) corrupt

Hi,

i have a problem with access xp (2002) database files after moving the files
to the linux files server. really often (6 times today) the database file is 
corrupt. 

i am running samba 2.2.5 on linux mandrake 8.2 with kernel 2.4.18.

i have read that this has something to do with the file locking, but don't 
know what to do right now.

i've set the parameter "veto oplock files = /*.mdb/*.ldb/" with no
cure...

is there a general guideline what to do work with access, or is this all
trial and error? Is there a reasonable log level to track down the problem?

thanks for any hint,

Joachim B?ddeker
