samba - Apr 2004 - How to reduce the memory used by Samba and its connection ?

Dear Sir :
    About the Samba, could you do us a favor to advise us if any comment about
the following problem.
    We used Samba v2.0.7.

    We are porting the Samba into Linux box.
    The Linux box is an embedded system with 32MB memory only.
    Because Samba takes around 1.5MB memory for each connections, it takes lot
sof memory for multiple connections.
    It exhausted the memory of box.

    In order to increase the NO# of connections of Samba in this Linux box, we
try to reduce the memory size of Samba.
    But it is really a big efforts.

   Could you do us a favor to advise us if any comment to reduce the memory size
for Samaba connections ?
   Thank you.

Best Regards.

Subject: [Samba] Fw: md5 fail on large file
Message-ID: <Sea2-DAV63HZOzTBoLI000250bc@hotmail.com>

Me again. I have upgraded to linux kernel
2.6.5. However this problem hasn't gone away.
The md5 check is fine, coping the same file
from NT4TSE to a Windoze 2000sp4.
Coping the same file from a windoze 2000sp4
to the samba share is ok. So the problem is
between NT4TSE and samba.

NT4TSE --> SAMBA = KO
WIN2k  --> SAMBA = OK
NT4TSE --> WIN2K = OK

Can anybody help me?
