Describe the Bug It seems that memory leaks happend when I trained my NAO robot with REINFORCEMENT LEARNING.

Could you please provide some additional details so that I can investigate the source of the leak?

• What controller are you using?
• Are you using an external script to run multiple scenarios for your reinforcement learning? If yes, what is it doing?
• Can you detail a little bit more the process of your algorithm: is it starting multiple instances of Webots, reloading the world multiple times, etc?

If you have access to a Linux machine, I suggest you to run your project there and use the Heaptrack tool which is very intuitive to find memory leak sources. Otherwise, if possible, you can also provide your project and I can have a look myself.

Thanks for your reply, I will do the same thing in my ubuntu18.04 with the help of Heaptrack.
