Pedsim Crashing Every Time it is run

[owen7900]

I am runing Ubuntu 18.04 with Melodic and the pedsim_ros master branch. I am running with a robot enabled using a modified small_airport scenario with 5 times less people and 10 times less in all dimensions.

[pedsim_simulator-1] process has died [pid 136, exit code -11

The above line of text was spit out along with this warning several times before crashing
[ WARN] [1589400517.323722476, 80.592000000]: Covariance matrix is not positive (semi-)definite in ProbabilityEllipseCovarianceVisual::setMeanCovariance(): Matrix3(0, 0, 0, 0, 0, 0, 0, 0, 0)

This is probably just a crash of the visualizer, can you run without visualization and check that the main engine works. If yes, can you share more details of the scenario you are running

[owen7900]

With visualization disabled it is still crashing after about a minute attached is the scenario file (renamed to txt). The simulation runs and all agents move around properly until it abruptly crashes.
tiny_airport.txt

Any assistance would be much appreciated.

Taking a look

I tested the scenario, and it seems like the walls are too close. And be careful to spawn agents within the limits of the world
