The scp or ftp start on a RT machine. The destination is an RT or Non RT machine, the problem is the same. It's not a space problem, I have 4GB available on the destination path. I can reproduce the phenomena at each try. If I <CTRL C> the scp when it is stalled then relaunch the scp command, the transfert restart without problem. I'm trying to trace this problem but I don't know how to do this. Has someone one method ?
