Can you include more details? Does it happen consistently? Did you use search or cmd+p before this? Other steps to reproduce?

[adwerrd]

I have also encountered this problem. it happen consistently. I can give you the process report created by MacBook Pro

[roblourens]

A process profile will probably just tell us that it's doing something in JS which isn't that useful. Did you use search or cmd+p before this? Other steps to reproduce?

I'd like to reopen this issue. After the latest update, I'm seeing this all the time.

The steps to reproduce would be:

1. Start Code
2. Open any Javascript file
3. The Code process jumps up to around 100% CPU usage and stays there.

I've disabled all of the extensions that I have installed, but these are the one's I'm using

$ code --list-extensions --show-versions

@gtb104 Is this 1.13.0? Which OS? What are the command line arguments of the process?

[Limoer96]

My Code version is 1.13.1, the code helper problem also seem at this version, it's memory usage also very high, almost 1.4GB! The OS is macOS 10.12.2.

[chrmarti]

@xiaomoer What are the command line arguments of the process?

[wuliupo]

it happen consistently

[chrmarti]

@wuliupo Could you open a new issue and include the command line arguments of the process? Also check if it still occurs with extensions turned off (Launch with code --disable-extensions). Thanks.

[gtb104]

I've recently updated to 1.13.1 and it seems to be much better. I'm on OSX 10.11.5. Don't know about the command line args. I always start it from my Dock.

[gtb104]

What I've noticed is that, even after closing VS Code, there are still some instances of Code Helper hanging around that are consuming upwards of 100+ % CPU.

[wmertens]

@chrmarti I have the same problem, here are the command line arguments:

[wmertens]

The high CPU one was the bootstrap one, I killed it (regular kill signal) and that closed the other Helpers too. Using latest stable VSCode on macOS 10.12.4.

[chrmarti]

@wmertens Could you open a new issue (Help > Report Issues to get things pre-filled)? That must be a new problem, would be great if we could track that separately.

[350050183]

Version 1.15.1 have the same problem on Mac OS X 10.12.6. After quit vs code, there are still two Code Helper processes not killed.

[wmertens]

I just had one now, I'm suspecting eslint or prettier. These were the
command line arguments:

Interestingly, it went away when I killed it with the normal kill signal, I
didn't have to use -9.

Also note that this seems to be 1.15.0 and I'm now on 1.15.1; it must have
remained after the upgrade today.

[zhenjia-boolean]

some problem, have you find a way to fix this ?

[paladin2005]

Same here, please fix this, very annoying quit vscode and still Code Helpe consuming >100% CPU

[offero]

Still happening for me sometimes.

[WolffDev]

I fixed this by killing all Code Helper's via terminal and then disabled Prettier - JavaScript formatter plugin.
After VS Code has restarted, it's not happening any more.
VS Code v. 1.17.2

[bihnkim]

Manually killing the problematic Code Helper process now pops up an error message on VS Code that an extension host has stopped. If I dismiss the notification without Restarting the Extension Host through the button, it does appear that Prettier stops working, so maybe that is the culprit.

EDIT: Sorry, I take that back, this problem has returned.

[davrodfer]

I have the version 1.17.2 and this problem has returned. I don't have any extensions installed and witout open any file the problem persists

[davrodfer]

The process responsible is this:

/Applications/Visual Studio Code.app/Contents/Frameworks/Code Helper.app/Contents/MacOS/Code Helper /Applications/Visual Studio Code.app/Contents/Resources/app/out/bootstrap --type=watcherService
