Nice, so it first spawns 1 vehicle then spawns -1 vehicle, seems optimal to me 😄

This seems like an issue of the vehicle spawner that it actually tried to spawn a motorbike. I'll take a look.

I'm not able to reproduce. I also noticed that in the last episode you actually requested 20 vehicles.

I don't know how that would happen. I don't change the configuration file.
I noticed that the last episode was run with something like a default configuration.
20 vehicles, 30 pedestrians, weather 1

Anyway
I tried again also disabling the bikes. I haven't seen the crash in 24 hours.
I am still having some weird connection problems. But this could be on my side.
I will retry with version 0.8.2

Thanks.

So, conclusion.
You should set the flag:
conditions.set(DisableTwoWheeledVehicles=True)
Without this flag, it seems CARLA can crash even without vehicles..

Still worth noticing that there is a bug in the current vehicle spawner. We are not fixing it for now as the vehicle spawner is most probably going to disappear in the 0.9.0 release.
