@alonabrany, since this is probably OS specific, please mention which OS you are using exactly. [oops, I wonder how I did not see that @lichtwerk asked that already ^^]

Well, you have the crowdrender addon installed, but I don't think this is related.

What happens when you stop these processes manually? Does the currently running Blender stop?

Do all the Blender instances really fill up your RAM, or only the "active" one?

I think Crowdrender may very well be related, I believe it starts a separate process. Please see if it still happens when disabling that add-on.

For future reference for all devs involved, this problem is indicative of the usage of the python multiprocessing module on windows, what it tries to do is spawn a new python interpreter by starting another copy of the currently running process with some extra parameters, sadly in our case, the running process is blender.exe and blender doesn't get any of the python specific command line options soo that ends up working really badly.
