Carla [0.9.2] getting slower after each repetition of scenario_runner #37

In scenario_runner --version 0.1. I found that the FPS of Carla Server drops after every repetition. I think the problem being that actors are not properly destroyed from the server. After the end of scenario I get this output:

LIFETIME: WARNING! the following objects were not destructed. 
LIFETIME: Actor 168 (sensor.other.collision) still alive. 
LIFETIME: tcp client 94 still alive. 
LIFETIME: Actor 163 (vehicle.tesla.model3) still alive.

I am doing actor.destroy() and actor = None after each repetition and they are being destroyed (I cannot see them in the server) but the memory still not being released and I get above output.

Could someone help me how to destroy the actors properly??

I'm seeing the same problem when using Carla from the normal client API.

@Danmou you are correct this is happening with me too.

fabianoboril commented 5 years ago

@anshulpaigwar @Danmou Does this problem still exist when you use CARLA 0.9.4 and the latest version from the development branch?

Could you please provide the exact setup that you use? CARLA version, how you start CARLA, what kind of client do you run etc. Thank you.

This is happening to me as well with Carla version 0.9.5
