VsCode often randomly renders entire system unresponsive, and then crashes - while not even using it

php4fan commented 3 months ago

Does this issue occur when all extensions are disabled?: impossible to tell

VS Code Version: 1.90.0
OS Version: Manjaro Linux

Steps to Reproduce:

I have VSCode open, with a project open, but I am not using it at the moment
I am using other applications and often Chrome, with several tabs open

Suddenly the entire system becomes sluggish. The mouse cursor moves slowly, clicks on anything in any application take long to respond and sometimes just don't. When I manage to open a terminal or a virtual console and run top, usually I'll find a "kswapd" process consuming 100% CPU, and then some other apparently random process/es, not always the same ones, also consuming several 100% CPU. The last time it has happened, besides kswapd, it was NetworkManager.

After a few minutes and usually before I have the time to actually do anything (because it takes long to even be able to open the terminal in the first place), everything goes back to normal, and then I realize that VScode is no longer open, that is, it has crashed. Which is what tells me that it's probably the culprit (which otherwise I would have assumed to be Chrome because it was the application I was actually interacting with). The only application that systematically crashes every single time when this happens, and the instant it crashes everything else goes back to working normally, is VSCode.

Usually, perhaps even 100% of the times, this does NOT happen while I am actually interacting with VSCode, but while it's open and idle doing nothing.

Please run code --status next time this happens and post the output here. Also see https://github.com/Microsoft/vscode/wiki/Performance-Issues for more information.

It happened again, so I did, but the command got stuck for several minutes producing no output, until the system went back to normal, then it produced the output below. This time VSCode didn't crash.

I tried but when this happens it's impossible to open the dev tools because the entire UI of VSCode is completely unresponsive. I hit F1 several times but the menu wouldn't show up.

php4fan commented 3 months ago

My suspicion is that this has to do with some weird interaction between VSCode and Chrome, and this is based on two observations:

the first few times that this happened, it always ended with VSCode crashing, and no other app ever crashed. But the last few times that I have observed this, VS hasn't crashed anymore.
in a couple of occasions while this was happening, I killed Chrome and this immediately resulted in everything going back to normal

Hey @jrieken, this issue might need further attention.

@php4fan, you can help us out by closing this issue if the problem no longer exists, or adding more information.

php4fan commented 3 weeks ago

It's been a while since the last time it happened. I guess I'll reopen if it happens again.
