network crash using smbclient

[Philippe Bertin]

Andrea,

Apparantly you loose your network ip address ? What does
/way/to/your/startup/scripts/network start
or
/sbin/ifup eth0 (your problematic network interface is eth0, I guess ?)
give as a result when you have these network problems ? Do you get your 
network capabilities back ? I can hardly imagine that samba would be at 
the origin of the problems that you describe ?

I may be (quite) wrong, but from what you tell, I'd rather suspect some 
problems with your network interface(/driver) which probably only shows 
up whenever *sending* big files over that interface ? Are you sure you 
use the correct driver for your interface? Do you have an idea if the 
same problem would occur when sending over the big file using NFS ? If 
using samba for sending over the file, are you sure the problem really 
doesn't always occur at the *very* same place ?

Kind regards
