As Avati points out, that's the EOF marker so it's fine.  It might be
interesting to run this on the client as well, to see how those values
relate to those on the bricks - especially at the point where you see
skipping or looping.  You might also want to modify it to print out
d_name as well, so that you can see the file names and correlate things
more easily.
