I found what was my problem (cfr previous post about network crash copyng FROM 
smb server TO local)

The problem is the buffersize.

I don't know how it could be, becouse it is declared as the buffer used in 
send/transmit, but actually it heavily ipacts on receiving files.

Some tests:

b=1200: copied 8.3GB in 33 minutes
b=16380: copied 8.3GB in 6 minutes
b=32700: copied 8.3GB in 4 minutes
b=65000: crash !!!

default is 65535 so thats way I am getting crashes

i also put debuglevel to 3 and specified log to use: if you are interested, 
look at the following files: they are the logs obtained using b=32000 (good) 
and b=65000 (crash)

thanks all,

Andrea
