Hi Thiago

I love that you included your scenario code and complete information about
software versions. Every questioner should be doing that.

We run this scenario for 4,000 seconds, but the simulation ends at 2,099

Even if you don’t see “any other insights”, it’s still valuable to provide
GDB ‘bt full’ output on Gist or PasteBin.
Also, try Valgrind as well in case it’s an memory error.

Increasing the number of nodes makes the simulation crash at an earlier
> time.
This raises suspicion on a memory allocation failure.

Yours, Junxiao
