samba - Apr 2003 - profiles for win98 + xp in same dir under home dir?

Does the following setup have any chance of ever working without to many 
problems?

Our mix of ~ 40 workstations (win98se & xp pro) get the home drive 
mapped in the netlogon script when connecting into the domain
for win9x
net use h: \\linux\homes

for win xp
net use h: \\linux\homes /persistent:no

relevant sections of our redhat 7.3 w/ samba 2.2.8 smb.conf are:

[global]

;; server name
netbios name = LINUX

;; we have win xp home as well that can't login to domain
security = user

domain admin group=@domadm

;;
;; Support for NT/2000/XP
;;   Note: registry changes may still be necessary
;;
add user script = /usr/sbin/useradd -d /dev/null -g 100 -s /bin/false -M %u

;;
;; Support for Roaming Profiles
;;
logon drive=z:
logon home=\\%L\%u\profile
logon path=\\%L\%u\profile

;;
;;  Domain logon support:
;;
domain logons=yes
logon script=logon.bat
domain master=yes
preferred master=yes

[homes]
comment=Your home directory

[netlogon]
path=/usr/local/samba/netlogon
comment=Domain logon service
browseable=no
read only=yes
write list=root

We have multiple users loging, one after the other throughout the day, 
from the same workstations into the domain, but those same users also 
occasionally login from the "other OS". (meaning even if their normal 
machine is win xp pro, they might occasionally logon using a win98 machine)
BUT according to "smbstatus -b" we appear to be having a number of 
"ghost" smbd sessions after running this setup for a few days. It 
appears as if the workstations keep connections to the server open even 
if those users have already logged of the machine and another user (or 
users) have since logged in from that machine. And after about 3 days 
everything comes to a crawl and we have to restart the samba server and 
that on a dual p4 2.4GHz with 1GB ram but only around 40 users or so on 
it at any time.

Is the way we have setup our profile share being under the users home 
dir contributing to the problems we have? The samba 2.2 PDC FAQ made me 
think that, but I am not sure I understood it correctly.

Any suggestions corrections instructions pointers or insults gladly 
received.

Thanks.

Yes normally, except on one xp pro machine. Why does running 
roaming profiles help or worsen the impact of having one's profiles 
under the homedir?

Thanks. I have put that in and will see what happens. But I was 
under the impression that the former smbd were never zombies 
.... they somewhow kept "working" for days and for users that 
had long since logged off those clients, as if win xp wasn't 
clsoing all it's connections to the home drive when a user logs 
out of a client and even apparently maintaining that connection 
past the time new users log in to that client.

I guess I mislead you with my language in the initial post. I used 
the word "stale" connections... well I used that as in "should
have
been closed a long time ago", but asfar as ps goes they were 
still alive and kicking ;-(

This is a reply I got as a direct reply which didn't go to the list.

Are you using "roaming profiles"..?

I would include the following options in your smb.conf

  keep alive = 160
  dead time = 240

Set the "number_of_seconds" to your need's, Do some reading 
about them in
you smbd man_pages...

Secondly, What you could do is to simply write a small Perl or 
even bash_script to run from cron every 5min's or so to look at 
processes and check the smbd ones status and if "zombie" then 
kill -9 "that_PID". You could also use substrates output to make 
your process activity checking even better...
