win95 + linux oplock error, even with kernel oplocks = no.

[Housebee]

Hi all,

I've posted a similar message a few weeks ago. I had the 'oplock' problem. I run a linux server with samba (specification below). I get a reply
who told me to disable kernel oplocks and oplocks. I did exactly what he told me to do.
I hoped it worked... but it did not... From there one i started reading in the archives and followed the 'lock' discussions in this list. I've t
ried a lot of options. I even got myself a CVS samba, because that (so i've read) would solve the the oplock 'bug', but still no luck... I don't
 know what to do anymore.

Allright, here is an overview of the layout of the small network.

Ik have 12 win95 client (a school class), and one debian (sid) linux server.
See here for the server specs:
        Samba version: 2.2.3-pre
        hda: QUANTUM FIREBALL ST1.6A, ATA DISK drive
        cpu: Intel Pentium 75 - 200 stepping 05
        Memory: 61732k/65536k available (1407k kernel code, 3416k reserved, 477k data, 204k init, 0k highmem)
        kernel: 2.4.4

fstab entry:
/dev/hda1       /               reiserfs        defaults,errors=remount-ro 0       1

There is a directory /opslag
drwxr-xr-x    4 nobody   nogroup       160 Nov 12 14:28 bak/

In this directory are the files which more clients at the same time have to acces. But as you might expected, only one client is allowed to do s
o, if an other client tries to access the same file, it gets a time-out or crashes.

I tries it with win98 and there were no problems. Only win95 has the oplock problem. Can some pls take a look at my problem.. I would be very gr
acefull if someone could straighten things up for me.

Below is my very small smb.conf and a log output from the moment things went wrong. I hope i've given enough information.

Thanx in advance
Housebee

Here is a bit from the log produced when two client tried to access the same file.
