/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.
