write_socket_data: write failure. Error = Broken pipe

[MCCALL,DON (HP-USA,ex1)]

Hi Carlos,
Since you are in Security=server mode, the problem COULD be that the broken
pipe
messages are indicating that you lost your connection from this smbd to the
password
server; every time a smbd sends a keepalive packet to a client, it
'piggybacks' a 
keepalive to the password server, and if that connection is broken, you get
this 
message.  This is fixed in the latest Samba 2.2.x; and can be avoided by
explicitly
adding the "keepalive = 0" parameter to the global section of smb.conf and
restarting 
samba.
This is just one possibility - I mention it because of the spacing of the
broken pipe
messages - almost exactly 5 minutes apart - some of the Samba packages out
there have 
a default of 300sec. for keepalive (like HP-UX), in contradiction to what
most of the 
man pages will say.  You can check this by running testparm and grepping for
keepalive
to see what the default on your samba installation is.
Hope this helps,
Don

How to fix !?

My smb.conf is:

     ##START-OF-SMB.CONF
     #
     [global]
      workgroup = Samba
      server string = FileServer
      domain master = yes
      preferred master = yes
      os level = 65
      log file = /opt/samba/var/log.%U
      max log size = 32
      security = server
      password server = sambapwd
      socket options = TCP_NODELAY
      dns proxy = no
      deadtime = 120
      wins server = wintwins
      include = /opt/samba/lib/U.%U
     [homes]
      public = no
      printable = no
      browseable = yes
      guest ok = yes
     #
     ##END-OF-SMB.CONF
