I will be interested in the responses. I have an issue with dbf files where the Samba Server
maintains a lock and has to be rebooted to release.

Sirs:

We are a Vinyl window manufacturing plant in central Washington State,
USA.  We have been running linux with samba for file and print
services for eight or ten years now.

Much of our production software is in house, and built on CA clipper
5.2, using dbf files as the primary data store.  The clipper dbf file
format supports both record locking and file locking along with shared
file access.  This worked very well on Novell netware and was working
ok on samba 3.0.23.

We had a samba server running for several years.  I believe it was
6.06 with samba 3.0.23 although I'm no longer certain of either of
those two versions.

We have about six stations running dos 6.22 and four running windows
98.  They are part of production machines, and changing the operating
system is not an option.

I had managed to tweak the samba config file so that file sharing
wasn't a big problem, the system was responsive and running fairly
smoothly.

We have numerous clients running winXP with no obvious problems.

We are, and have been running the Samba server with User validation.
We are part of a windows domain, but haven't figured out a way to have
the dos machines login as domain members.  The xp stations use the
domain for authentication, then we maintain a parallel set of logins
on the linux box and samba file server.  Again, this was working OK,
pre crash.

A month or so ago, we lost two hard drives on the file server and had
to do a rebuild.  I had tried to update the samba version a time or
two in the interem and failed.  I couldn't get the dos machines to
connect to samba and access the necessary data files.  One gentleman
on the samba list said that this was a problem with lanman protocol,
and aparently fixed it.  Samba 3.4.7 allows logins file access without
any problems.

The current problem is that shared clipper files are very slow.  It
appears as if record locking instead of file locking isn't being
recognized by Samba. When production is going, 20 second delays for
file access are common.  This was not true six weeks ago before the
server crash.

I have studied on the smb.conf file at great length, trying several
variations without sucess.

Any advice or hints of what to study now would be most welcome,
