[Samba] connection disconnects

[Sameer Kamat]

Hello,

   I would really appreciate any help since I am not able to debug this problem. We have a windows 2003 machine talking to a samba share exposed by Fedora Core 2. If I transfer a 5 GB file, it starts the transmission and then stops, sometimes at 1GB sometimes further around 3-4GB. The smbd.log file from the server show the following errors.

This is the smb.conf file :

[global]
    smb passwd file = /etc/samba/smbpasswd
    passwd program = /usr/bin/passwd %u
    pam password change = yes
    obey pam restrictions = yes
    encrypt passwords = yes
    unix password sync = no
    security = share
    socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
    preferred master = no
    server string = Samba Server
    load printers = no
    username map = /etc/samba/user.map
    log file = /var/log/samba/%m.log
    name resolve order = host
    smb ports = 139

[samba]
    path = /samba
    writable = yes
        guest ok = yes
    guest account = root



Please advise.

Thanks,
Sameer
