5MB/minute memory leak when keeping the process explorer open

[officiallymarky]

Issue Type: Bug

I have 45 extensions installed and applications start to crash after leaving VS Code running for 2-3 days, if I have more than one instance it is sooner.

I assumed it was an extension as I have 45 installed. My initial reaction was to disable GitHub CoPilot thinking this might be the problem, and no change in memory loss. I am using VS Code Process Explorer to monitor memory usage.

So my next step was to disable all extensions and enable them one by one to see if I can catch the one giving me a problem. While waiting a few seconds for a baseline with no extensions, I noticed I was still losing about 5MB/minute or just over 300Mb/hour.

I am using latest version on Windows 10 Pro x64 with latest system updates. I have tried a fresh reboot and running without extensions on a fresh restart and I am continously losing ram at the same rate. With all extensions enabled, I am losing roughly the same amount of ram per minute.

I've been having this issue for a few months and doubled my system ram to 64G to give me more buffer until things start crashing as at the time I haven't narrowed down the problem.

UPDATE:
I installed the insider build and seeing similar results, in fact memory loss is closer to 5.9MB/minute. This is without extensions and with default settings file. Just sitting idle without a project loaded.

@officiallymarky thanks for the report. From the process explorer, do you see which process is consuming more and more memory? A screenshot would probably help and we can check if it's a UI process or an extension process.

I disabled all extensions, and even ran insider with default config and no extensions.

It shows all the memory on the code parent process, but doesn't seem to show which one.

Here is a blank project (nothing loaded, just started code and left it idle) in Code Insiders with default settings and no extensions before and after a couple of hours (~3 or so)

@officiallymarky the screenshots are very helpful, thanks!

I still see it with latest update, also I see it in the insiders build. Has something been identified that is causing this?
