Just a thought, does using ssh from ports make any difference?  Do you have
any more info about the threshold of file size for when this problem starts
occurring?  is it always the same?  EG if Vbox has 2 GB mapped out and you
get an error at a certain file size, does reducing the Vbox memory footprint
allow a larger file to be successfully sent?
