Yes. Making such list is not a good idea I think.
Seems you all debate here of what the causes of the malfuntion could be
(or are), and I think you didnt understand my point of view. Seems you
arent considering all of the problem. (read above).

Sure. But you can't forbid people to drive because one of them maybe one
day will drive drunk :-)
I mean, in a production environment, It cant be half answers. It works
or it doesnt. Thats my point of view.
It is really interesting to know more about oplocks, why it works or
not, why this client OS, this application will fail with oplocks on.
And I really thank you all to share your knowledge on this!
But, again, I cant bet on a technology. I'm not playing poker and cant
do it with files where maybe all the business of my company is based on.
Thats why I've disabled oplocks.
I'm DBA maybe you'll understand why my principal fear is data loss. :-)
Thanks all again.
