I used to see this all the time-- still do sometimes. Was made slightly 
better for me by adding to smb.conf this line:
smbports = 139

This makes it not try to use port 445. Without this, it tries both more or 
less simultaneously, then uses whichever one answers first.

If you are having similar symptoms to mine, attempts to copy a large file 
will cause it to write a zero-length file then bark at you about the 
network connection no longer existing. Retry the same operation within a 
few minutes, and overwrite the zero-length file, and all is well, even if 
you are copying dozens or hundreds of files.

I'm stuck with Samba 3.0.9-2.5 at the moment.
