This is an interesting enough problem that I have been going through my
photo literature looking for some reference to this.  In the 15th edition of
the Leica Manual ('73) Bill Pierce's article on developing and printing
mentions this as a sign of uneven development.  One possible source could be
using a tank that does not have a full compliment of reels.  The film
sloshing back and forth during agitation could pump developer through the
sprocket holes.  The streaks are dark on the print where the sprocket holes
should be indicating more development on the negative in those areas.  (The
second bath could still be the culprit since the film is typically
unagitated during that bath.)  I think it might be the short time in the
first developer.  You might try diluting the D-76 1:1 for longer developing
times.  This is what Bob Schwalberg recommended in an old article I have.
(Pop Photo's "35mm Photography", Spring, 1974.)  He used plain water for the
second bath.  Hope this helps.
