@alon abrany (aabrany), since this is probably OS specific, please mention which OS you are using exactly. [oops, I wonder how I did not see that @Philipp Oeser (lichtwerk) asked that already ^^]

@alon abrany (aabrany), have you installed any extra addons?

Please, upload your full system info, you can export it from within Blender with Help -> Save System Info.

Here are my pc details

No addons installed

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?

only one processes is relevant the other are like a by-product ,of the comands.

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.

look at the image , every one takes 53,000

Hi Brecht .
You 're right. It really happened because of Crowdrender .
Thanks for the help

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.
