We have been using SAMBA for file/print servers and domain controllers
in Windows networks for several years. At one site, we have
intermittent problems in which the connection to the SAMBA server
appears to die: i.e., no one can connect to the share, and the Windows
clients (Terminal Servers and workstations) apparently keep re-trying to
connect which ultimately locks up those clients.
They have about 20 or so users, mostly doing MS Office stuff, opening
one very large MS Access database (around 400 Mb) and using a lot of
Outlook PST files - some over 1 Gb each. All of this data, as well as
their roaming profiles, is stored in the 'base' share listed in smb.conf.
We have noticed in many cases, but not all, that there is an error in
/var/log/messages indicating that the samba process had an error and
apparently the process exits. I've included a sample from
/var/log/messages. In this case, we are using (2) Windows 2000 Terminal
Servers, as well as one XP workstation. The OS on the SAMBA server is:
Mandrake (Linux version 2.6.3-7mdk-p3-smp-64GB
([EMAIL PROTECTED]) (gcc version 3.3.2 (Mandrake Linux 10.0
3.3.2-6mdk)) #1 SMP Wed Mar 17 15:34:39 CET 2004), and the SAMBA version
is: 3.0.2a. We also had the same problem using Fedora (Linux version
2.6.9-1.667smp ([EMAIL PROTECTED]) (gcc version 3.4.2
20041017 (Red Hat 3.4.2-6.fc3)) #1 SMP Tue Nov 2 15:09:11 EST 2004) with
SAMBA 3.0.8pre1-0.pre1.3.

;This next setting stands for /client-side caching policy/, and
specifies how
; clients capable of offline caching will cache the files in the
; share. The valid values are: manual, documents, programs, disable.
; These values correspond to those used on Windows servers.
; For example, shares containing roaming profiles can have offline
; caching disabled using *csc policy = disable*.
; Default: //csc policy/ = manual /
; Example: //csc policy/ = programs /
csc policy = disable
