/proc/602 is a system directory associated to the process number 602. I 
guess du first finds 602 inside proc when listing the directory /proc, 
then tries to open it. If 602 is a transcient process (that is it runs 
for a short time), it may happen that it has disappeared before the 
second time it is accessed.

You may add --exclude=/proc to the command linen but I think it is harmless.

Pierre
