Yes, that was very useful.  Strm=1 is the main attribute info and Strm=10 is
the SHA1 digest.  I would expect Strm=10 to occur after Strm=1 for each value
of FI.

It looks like the Director isn't receiving the SHA1 for the broken file.  The
FD generates the SHA1 and sends it to the SD, which then writes it to the
volume and sends it to the Director.

Running the FD with debug level 400 might help to see if it generates the SHA1
at all.
