The ssh connection used for copying (using the command <ssh old_pc "cd
/directory; tar cvf - *" | pv | tar xvf ->) died in the following way:
   ...
   Read from remote host old_pc: Connection timed out
   51.4GB 4:26:19 [3.29MB/s] [<=>                                   ]
   tar: Unexpected EOF in archive
   tar: Unexpected EOF in archive
   tar: Error is not recoverable: exiting now

and there are currently no traces of those ssh processes any longer on
the new PC, only these two active ssh interactive connections are present:

On the old PC there are three corresponding zombies:
