Upon further investication, I ran a 300 second test, where the results summary
only considered the first 170 seconds. Upon checking the output of the test, I
noticed this at the 170 second mark.

Any thoughts?

Attempts to resolve this using ulimit -n 99999, and increasing the
kernel.max_threads value in sysctl.conf didn't work properly. I'll be looking
into how the results are parsed, and see if I can't get the program to ignore
thrown exceptions.

Hi.. just saw this issue. sorry for the late reply.
do you only see this when launching 400 threads, or does it ever occur at lower
levels? It looks like it can't spawn new threads after a certain amount.
(I've definitely launched > 400 threads, but not on EC2)
how much RAM does your EC2 instance have? have you watched memory on the box?

Sorry about the late feedback. The ec2 instances were basic... not very beefy.
I've since started using bigger boxes with more processors and more ram.
