Help! oplocks issue

[Gary S MacKay]

We converted a 40 user network over from Netware to a new RedHat 7.1 server
running the latest Samba 2.2.2. This morning when multiple users tried to
run a database app (uses standard dbase III type tables) the app blows up at
random places. I presume this is a file locking issue since one user can
work fine. With the new version of samba, what are the proper settings
supposed to be in the smb.conf file for oplocks, kernel oplocks, etc,.
etc..??

I have a bunch of very angry women after me! Help!
