Hmm, my gut instinct here is to look at oplocks and how they are setup
on your server. I had a similar issue with quickbooks a long time ago -
this is one large file that can be worked on by several people
simultaneously, and we had to fix it with oplocks. I can't recall
excactly what was done, but that might at least get you in the right
direction. In our case, I do know we had to seperate that QB file out
from the rest of the files and create a "special needs" share that was
different. Come to think of it, I think we totally disable oplocks...
but, you really ought to read about them to find out what's needed and
what's not.

Hi,
I'm managing a Samba server for almost 4 year now and I've got some
glitch with AutoCad & Samba, but I've found many solution to solved
those problems. Last week, I receive many complains about some users
that experience problem using AutoCad. In fact, it's not AutoCad but
Advance Steel Metal 2009 (plugin for AutoCad). In this new version of
Advance, there is a new feature called Model Sharing. This feature
consist in a support of multiple user sharing the same file -
concurrent modifications can be done by multiple user. I'm not really
sure how it's implemented, I'm still in process to get access to some
implementation details.
So far, our investigation point that Samba may be in cause. I think
it's related to some flag not supported by Samba or implemented
differently to the MsWindows.
This problem is a big issue for us and I want to do everything
possible to fix this problem (what ever it's Samba related or AutoCad
related.)
To proceed, I need some help from Samba team to debug the problem with
me.
How can I have detailed logs showing the open flag ?
Is a tcpdump can be usefull ?
Is there any configuration to support shared mode ?
I have a look at this documentation, does Samba support every flags ?
