Hello List,
Please read Tom's email below. Has some interesting
findings. The affected
machine I dealt with also had symantec on it. Since the
repair though there
hasn't been a problem. The user even re-applied the
patches. This is to weird.

Jim, sorry to keep doing this to you but the Samba list
rejected me
again. Please share this with the list.
Thanks!

Here's what we've discovered about this problem, including
much new
information:
(Most of the tedious version details are deferred to the end
of this
message for readability.)
(Dates are expressed American-style as MM/DD/YY.)
On Thursday April 5th our users started experiencing abrupt
reboots
(without proper shutdown) when they copied, saved, or
renamed files on
our Samba 3.0 shares. This Samba server has run flawlessly
for years in
essentially the same configuration as now, and exactly the
same
configuration since Christmas. The problem does not occur
when writing
to Microsoft or Novell shares.
After trying various experiments on the affected
workstations, we
determined that the problem always and only occurs on
workstations which
are running both the Novell Client and Symantec AntiVirus.
We can only
induce the problem by installing both, and removing either
one always
cures the problem.
Regarding Symantec, we have determined that it was a virus
definition
file from soon after 3/27/07 (probably one from the week of
4/2/07) that
triggers the problem. The current program version and scan
engine
version with virus definition files earlier than 3/27/07 do
not trigger
the problem.
Regarding the Novell Client, we have found that only a
default
installation is needed to replicate the problem -- no need
for Zenworks
client, or even to log in. Also, moving the Novell Client to
the bottom
of the "provider order" list does not fix the
problem.
Although the timing of the problem's first appearance
corresponds
suspiciously with the release of Microsoft's patch KB925902,
we have
eliminated this patch as a factor.
We have another Samba server, version 2.2 running on
Solaris, whose
users do not experience the problem. So we tried setting up
another
Samba 2.2 machine to test with -- in every way similar to
our Samba 3.0
machine except for the Samba version. We cannot replicate
the problem
when writing to a Samba 2.2 share, regardless of workstation
configuration.
Although there are a few contributing factors coming
together to create
this problem, we believe that the most likely and
appropriate solution
would come from Symantec (e.g. in the form of a fix to their
virus
definition files). However, fixes might also be possible in
the Novell
Client or Samba.
Hope that helps someone and/or someone can help me!

Appendix: The software versions tested are:
* Windows XP with Service Pack 2 (no
other versions tested)
* Novell Client version 4.91.3.20061109,
default installation, no Zenworks client
* Symantec AntiVirus: program version
10.1.5.5000, scan engine version
71.2.0.12, and several virus definitions
between 4/9/07 (and surely going back
into the week of 4/2/07) through at least
4/16/07 rev 17. Virus definitions earlier
than 3/27/07 (and probably earlier than
the week of 4/2/07) do not trigger the
problem.
* Samba version 2.2.5 (installation method
and options unknown, running on Solaris)
-- NO problem
* Samba version 2.2.12 (default installation
from samba.org source code, installed on
Slackware 10.2) -- NO problem
* Samba versions 3.0.23d and 3.0.24 (default
installation from samba.org source code,
installed on Slackware 10.2 and 9.1
respectively) -- DO have problem
