proc npar1way does not stop running

hi, not sure what is the issue here but for some reason the proc npar1way does not stop running even with low number of obs. Any idea?

below is a part of the final dataset:

675 smp
515 smp
548 smp
599 smp
500 smp
715 smp
500 smp
0 pop
100 pop
666 pop
100 pop
752 pop
648 pop
500 pop
500 pop
100 pop

data final;
set smp (obs=100) pop (obs=100);
run;

ods graphics on;
proc npar1way edf data=final;
class source;
var application_score;
exact ks;
run;
ods graphics off;

What happens if you take the EXACT command out and run it?

As you have observed, the EXACT statement can cause long run times in PROC NPAR1WAY. Adding the MC option to the EXACT statement requests a Monte Carlo estimate of the exact p-value. This calculation can be a good compromise when the exact computations are too computationally intensive to wait for. With the MC option, the exact tests will not be computed.
