Visual Studio Code took 10.7 GB RAM usage after using it for one hour

Question

It happened today when I suddenly noticed processes started getting slow on the computer. So I checked Task Manager to see what causes it.

I have waited a couple of minutes to see if it changes by keeping Visual Studio Code in idle state and then my computer dumps the memory in BSoD (blue screen of death).

After rebooting, I tried the same way to reproduce the state and within 20~30 minutes, it is up to 5 GB.

0 909 4452 c:\Users\arbaz\.vscode\extensions\ms-python.python-2018.12.1\languageServer.0.1.72\Microsoft.Python.LanguageServer.exe

What are the possible reasons causing this and how do I fix it?

Answer 1

This issue is mostly caused by the extensions.

Try to monitor menu Help → Open Process Explorer for a certain period to see which process name is taking large memory.

Try uninstalling all extensions and removing all their junk from %USERPROFILE%\.vscode\extensions for windows.

Answer 2

This problem happened to me yesterday. I managed to fix the problem, but I am not sure if my solution applies to yours. I'm using Windows 10 and Visual Studio Code version 1.33.1.

The solution is to go to settings and enable jedi. The culprit that was consuming excessive RAM was Python language server. So, by enabling jedi, instead of using the Python language server for the intellisense function, jedi was used instead.
