I don't believe the other threads are crashing, when I enable
statistics-interval I get 8 threads printed to the log. I went ahead and
enabled statistics-interval, with a 3 minute timer. You can see them
below, it does look like thread0 is taking most of the queries, but not
100% of them.
I also changed the config:
outgoing-range: 16384
num-queries-per-thread: 16384
