samba - Nov 2006 - Samba -> Linux copies fine, Samba -> Windows hangs all existing connections

I'm running Samba 3.0.23c on Debian-arm (unstable), kernel 2.6.18.

I can copy files from the Samba server just fine, when I do it from a 
Linux machine.

When I want to copy files from the Samba server to a Windows XP SP2 
machine (connection made from Windows), it copies a couple of files, and 
then everything just freezes - Samba doesn't send any more packets, and 
I have to reconnect all connections.

SSH connection is untouched, and this phenomenon concerns only files 
copied via Samba.

Anyone else seen this?

I solved it by setting:

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=4096 
SO_SNDBUF=4096

in smb.conf.

I wonder if it's specific to ARM?


When I usen 8192 instead of 4096, I had these mysterious hangs and 
disconnections.

Linux cifs clients had this logged by the kernel when it happened:

  CIFS VFS: No response to cmd 46 mid 1887
  CIFS VFS: Send error in read = -11
  CIFS VFS: No response to cmd 46 mid 3313
  CIFS VFS: Send error in read = -11
  CIFS VFS: No response to cmd 46 mid 4125
  CIFS VFS: Send error in read = -11
  CIFS VFS: No response to cmd 46 mid 4361
  CIFS VFS: Send error in read = -11
  CIFS VFS: No response to cmd 46 mid 4752
  CIFS VFS: Send error in read = -11

I have opposite situation, could get files from Windows but Linux fails, 
server runs FreeBSD. From other side I can get files using xsmbrowser 
but it still working very slow and I'm unable to download big file.

Any ideas what could it be?
