I've CC'd Rob and David.
You can find the FIO command lines used by running the script in verbose 
mode: it lists them all at the start, then steps through them one by 
one. Unfortunately nobody's had any luck in narrowing down a single run 
that causes the hang.
I forgot to say that the problem has been seen on FIO 3.1 - I never got 
around to trying it on version 3.5, which is now on 
https://bluestop.org/fio .
