Anyone get the following error running the openmp code on millinneum?

1751][jhammel@c42:~/CS267/html/homework-2/build/openmp]$ export OMP_NUM_THREADS=1
[1751][jhammel@c42:~/CS267/html/homework-2/build/openmp]$ time ./fish -n 400 -s 4000 -t 1.0
OMP abort: Unable to set monitor thread stack size to 65536 bytes.
Try reducing KMP_MONITOR_STACKSIZE or increasing the shell stack limit.

Aborted

Yes, I got that message. Try using:
env OMP_NUM_THREADS=4 env KMP_MONITOR_STACKSIZE=200000 openmp/fish ...

if it's not too late. I don't know why increasing the size fixes it, but I
have used this command and it worked every time.
