samba - Apr 2003 - Samba possibly causing windows 2000 to crash?

I am using the following:

Samba 2.2.8a (from FreeBSD ports)
FreeBSD 4.7-RELEASE-p10

Samba is configured as a member of a Windows 2000 domain.

Generally everything seems to be working as expected.  Occasionally the
following gets logged to the console:

[2003/04/14 20:25:19, 0] smbd/service.c:make_connection(599)
  zulu (192.168.1.161) Can't change directory to /data/path (No such file or
directory)
[2003/04/14 23:22:50, 0] lib/util_sock.c:read_data(436)
  read_data: read failure for 26184. Error = Connection reset by peer

But the clients do not seem affected by this.

However, when I try to backup our exchange 2000 database onto the Samba server,
using ntbackup.exe, the exchange server always crashes.  We are talking blue
screen of death here!

The Exchange server is running on Windows 2000 server with service pack 3 and
exchange service pack 3.

When the server crashes and begins to dump memory the following is displayed:
(hand transcribed so not word for word)

STOP 0x0000001E (0x0000005, 0x00000000 0x00000000 0x00000000)
KMODE_EXCEPTION_NOT_HANDLED

The machine then reboots, but no further error messages are displayed.

The exchange database is almost 7Gb but it never get past approx 4.5Gb as the
crash seems to always happen on the second file which I think is priv.stm.
The same backup operation works perfectly when backing up up elsewhere,
including onto a old(ish) Snap Server (very slow!), which from what I have been
able to tell runs an embedded linux OS and possibly samba!

The samba shares are also shared over nfs but these backups are performed at
weekends when the network is completely quiet.

Also of note, the shares are mounted on mirrored drives using Vinum for software
mirroring.

Any help would be greatly appreciated. Smb.conf is below.
