can you narrow that down to a bare minimum set?  2 or 3 requests maximum.

random tests find problems, however they are nonreproducible (unless you set
random.seed) which you should do.

then create a repro sequence and add a test specifically for that (short)
sequence.

not until i get an entire day looking at it, no.
