I've recently switched my account over to N-Body acceptance instead of just the other (i've now switched it off again though).

One of the simulations has been stuck at 28.231%, using 12 CPUs (all threads available, basically), for now 11 and a half hours, with the remaining time going up and up the more it stalls at 28.231%.
Is this expected behaviour, or has it crashed? I believe this may have been why i disabled N-Body in the past too, as it was taking far too long, on all threads, starving other tasks and projects of CPU availability.

If it helps, I run the following setup
Windows 10 Pro
Intel i7-8700
2x GTX 1070
16GB RAM
