[Serge Tremblay]

better late than never
I would suggest you take a look at the File and Record Locking section 
[http://us4.samba.org/samba/docs/man/Samba-HOWTO-Collection/locking.html] 
of the samba official howto 
[http://us4.samba.org/samba/docs/man/Samba-HOWTO-Collection/] (must read 
if you have not ;) ) regarding your database corruption problems

I hope this helps or that you already found your problem
