I'm having _exactly_ the same problem on my Alpha XL 366. I originally 
was running Samba 3.0.9-r1, which had the problem, and yesterday I 
upgraded to 3.0.11 to see if that would help, but it didn't. The problem 
still exists.

FYI, I have searched Google, and found no specific info on Samba and 
Signal 11, but what I did find was that Signal 11 (segfault) often 
happened when you have bad RAM. The thing is, only Samba ever exhibits 
that problem, so I don't think I have bad RAM or it would happen more 
randomly than that.

Perhaps someone more versed in Samba could help us. In particular, I 
know that when I installed Samba, I used the same config file I used on 
another install (another version of Samba, which was running on 
Debian-Alpha at the time). The config file seems to work fine (Samba 
doesn't complain, even when I do 'testparm') but I don't know if that 
could be a source of the problem. I am including my smb.conf just to see 
if someone could spot something that might cause this problem...

Anyways, if you ever find something, please let me know. I'll do 
likewise. And if anyone on the list has ever had this problem or can 
otherwise help us, we'd like to hear from you!

Thanks in advance,

J-S

smb.conf (text/plain, 12.2 KB)
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not many any basic syntactic errors.
#
#======================= Global Settings =====================================
[global]

##
## Basic Server Settings
##

	# workgroup = NT-Domain-Name or Workgroup-Name, eg: REDHAT4
	workgroup = WORKGROUP

	# server string is the equivalent of the NT Description field
	server string = Alpha Samba

	# This option is important for security. It allows you to restrict
	# connections to machines which are on your local network. The
	# following example restricts access to two C class networks and
	# the "loopback" interface. For more examples of the syntax see
	# the smb.conf man page
	hosts allow = 192.168.0.

	# Uncomment this if you want a guest account, you must add this to /etc/passwd
	# otherwise the user "nobody" is used
	; guest account = pcguest

	# this tells Samba to use a separate log file for each machine
	# that connects
	log file = /var/log/samba/log.%m

	# How much information do you want to see in the logs?
	# default is only to log critical messages
	; log level = 1

	# Put a capping on the size of the log files (in Kb).
	max log size = 50

	# Security mode. Most people will want user level security. See
	# security_level.txt for details.
	security = user

	# Using the following line enables you to customise your configuration
	# on a per machine basis. The %m gets replaced with the netbios name
	# of the machine that is connecting.
	# Note: Consider carefully the location in the configuration file of
	#       this line.  The included file is read at that point.
	;   include = /usr/local/samba/lib/smb.conf.%m

	# Most people will find that this option gives better performance.
	# See speed.txt and the manual pages for details
	# You may want to add the following on a Linux system:
	#         SO_RCVBUF=8192 SO_SNDBUF=8192
	socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

	# Configure Samba to use multiple interfaces
	# If you have multiple network interfaces and want to limit smbd will
	# use, list the ones desired here.  Otherwise smbd & nmbd will bind to all
	# active interfaces on the system.  See the man page for details.
	interfaces = lo eth1

	# Should smbd report that it has MS-DFS Capabilities? Only available
	# if --with-msdfs was passed to ./configure
	; host msdfs = yes

        # Test to try and fix Signal 11...
	passdb backend = smbpasswd

##
## Network Browsing
##
	# set local master to no if you don't want Samba to become a master
	# browser on your network. Otherwise the normal election rules apply
	; local master = no

	# OS Level determines the precedence of this server in master browser
	# elections. The default value (20) should be reasonable
	; os level = 20

	# Domain Master specifies Samba to be the Domain Master Browser. This
	# allows Samba to collate browse lists between subnets. Don't use this
	# if you already have a Windows NT domain controller doing this job
	; domain master = yes

	# Preferred Master causes Samba to force a local browser election on startup
	# and gives it a slightly higher chance of winning the election
	; preferred master = yes


##
## WINS & Name Resolution
##
	# Windows Internet Name Serving Support Section:
	# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server
	; wins support = yes

	# WINS Server - Tells the NMBD components of Samba to be a WINS Client
	#	Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
	; wins server = w.x.y.z

	# WINS Proxy - Tells Samba to answer name resolution queries on
	# behalf of a non WINS capable client, for this to work there must be
	# at least one	WINS Server on the network. The default is NO.
	; wins proxy = yes

	# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
	# via DNS nslookups.
	dns proxy = no


##
## Passwords & Authentication
##
	# Use password server option only with security = server
	# The argument list may include:
	#   password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]
	# or to auto-locate the domain controller/s
	;   password server = *
	;   password server = <NT-Server-Name>

	# You may wish to use password encryption. Please read
	# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.
	# Do not enable this option unless you have read those documents
	  encrypt passwords = true

	# Should smbd obey the session and account lines in /etc/pam.d/samba ?
	# only available if --with-pam was used at compile time
	; obey pam restrictions = yes

	# When using encrypted passwords, Samba can synchronize the local
	# UNIX password as well.  You will also need the "passwd chat" parameters
	; unix password sync = yes

	# how should smbd talk to the local system when changing a UNIX
	# password?  See smb.conf(5) for details
	; passwd chat = <custom chat string>

	# This is only available if you compiled Samba to include --with-pam
	# Use PAM for changing the password
	; pam password change = yes

##
## Domain Control
##
	# Enable this if you want Samba act as a domain controller.
	# make sure you have read the Samba-PDC-HOWTO included in the documentation
	# before enabling this parameter
	;   domain logons = yes

	# if you enable domain logons then you may want a per-machine or
	# per user logon script
	# run a specific logon batch file per workstation (machine)
	; logon script = %m.bat
	# run a specific logon batch file per username
	; logon script = %U.bat

	# Where to store roving profiles (only for Win95 and WinNT)
	#        %L substitutes for this servers netbios name, %U is username
	#        You must uncomment the [Profiles] share below
	; logon path = \\%L\Profiles\%U

	# UNC path specifying the network location of the user's home directory
	# only used when acting as a DC for WinNT/2k/XP.  Ignored by Win9x clients
	; logon home = \\%L\%U

	# What drive should the "logon home" be mounted at upon login ?
	# only used when acting as a DC for WinNT/2k/XP.  Ignored by Win9x clients
	; logon drive = H:

##
## Printing
##

	# If you want to automatically load your printer list rather
	# than setting them up individually then you'll need this
	load printers = yes

	# you may wish to override the location of the printcap file
	; printcap name = /etc/printcap

	# on SystemV system setting printcap name to lpstat should allow
	# you to automatically obtain a printer list from the SystemV spool
	# system
	; printcap name = lpstat

	# It should not be necessary to specify the print system type unless
	# it is non-standard. Currently supported print systems include:
	# bsd, sysv, plp, lprng, aix, hpux, qnx
	; printing = bsd

	# Enable this to make Samba 2.2 behavior just like Samba 2.0
	# not recommended nuless you are sure of what you are doing
	; disable spoolss = yes

	# list of users and groups which should be able to remotely manage
	# printer drivers installed on the server
	; printer admin = root, +ntadmin


##
## Winbind
##

	# specify the uid range which can be used by winbindd
	# to allocate uids for Windows users as necessary
	; winbind uid = 10000-65000
