Could you send me a copy of the packets you're seeing?  That's usually
the easiest way to tell whats going on.  There are a handful of people
on the planet those debug messages make sense to :)

Would you perhaps only be seeing half of the packets ( via an ethernet
tap or asynchronus link ).

Since you are only interested in rebuilt packets, I would write a
preprocessor that throws away everything that fails
(p->packet_flags & PKT_REBUILT_STREAM)

A good pun is its own reword.
