Out of control CPU while using

[tekHudson]

Problem/Motivation

I heard the fan on my machine going nuts.

top showed 95+% CPU consuption with no process showing any consumption.

The htop didn't help much either.

Awhile had passed and the CPU seemed to have started to wind down (i was working so could only deal with this on and off).
I had a break so I went to VScode to check my logs and immediatly heard the Fan go nuts.

I looked at the VScode addon page

Expected behavior

Runs smoothly?

Actual behavior

I am also having this issue.

[PiotrMachowski]

I have also experienced this issue. In my case it seems to be caused by opening / directory instead of /config. Maybe it intensively indexes the whole root directory?

Same here (RPI 4b 8gb)
The addon was working fine until one of updates, since then I had to disable the addon as it consumes all CPU immediately. It's a pity as it was fantastic tool, sad to see nobody cares

[Egglestron]

Same issue found thanks to the Glances add-on: 10 GB of RAM and 80% CPU usage. Happened while going in and out of Visual Studio Code, maybe a new instance is launched every time.

This issue happens on my side too, by restarting the addon, the issue is solved. Also, Ram Usage seems also to be affected.

As soon as I open the VS Code Tab the usage spikes as seen below and falls down when closing the tab, but still rises without code being opened (instance running in background). I'm running on a Raspberry Pi 4.

same problem here... i was thinking problem was relate to HA core but now im sure its VS code. Im running everhing in docker container.

home-assistant/core#119796

I have issues with CPU too, but a little bit different. When watching the release party I saw a jump page with links to all Addons. I love the approach so I decided to create this too.

I have a entities card with :

type: entities
entities:
  - type: weblink
    name: Studio Code Server
    url: /hassio/ingress/a0d7b954_vscode
    icon: mdi:microsoft-visual-studio-code

This makes the page just start. But it seems it is not closing it. It just opens more sessions.

Is this the same issue, or the same cause, or should I open a new one?

[marciogranzotto]

@frenck can you release a new version of this add-on? Looks like this may be related with a bug on add-ons that use devcontainers. This was fixed back in April: microsoft/vscode-remote-release#9586

I experience the same issue,
but only if I open the folder /
If I open the default folder /config memory usage seems to be more stable

Yes I can confirm this too!
I think it has to do with the amount of files vs code (or the Home Assistant Config Helper extension) has to watch for or scan. So make sure you just use the correct folder in your workspace: Three lines => File => Open Folder... or just press CTRL + O and make sure you are working in the "/homeassistant/" folder

And if it is absolutely necessary change it to "/" only temporary, and don't forget to go back to the right folder afterwards :)

I've also noticed that the autocompletion feature served by the Home Assistant Config Helper extension does not work (an issue that multiple persons have complained about), if you are not in the right folder.

I spent hours banging my head around why the autocompletion did not work and why it used so much CPU 🤦‍♂️

Just my 2 cents :D

@frenck Could this be noted somewhere in the docs as some sort of warning to not use/open the root folder?

Feel free to open a PR.

Selecting /homeassistant/ as working folder doesn't solve the issue of high CPU usage in my case.
Not so long ago this add-on used to work all right with "/" as working folder (that's what I need). CPU usage was nearly 0% when not actively using VScode; right now I have to explicitly stop the add-on when I finish using it, otherwise it melts my rpi4.

[amagnolo]

As a workaround, I found the the "file editor" add-on lets you work in "/" files if you disable the default option "Enforce Basepath".
That add-on consumes 0% CPU when unused.

Still not solved, the addon is unusable, at least on RPI

[mhoogenbosch]

I'm using the 'workaround' too because I haven't seen a new release, or anything related to solving this issue. I'd rather use vscode, but very much not usable. I need to restart the addon every time I've used it.

[antoweb]

After last update same problem. My Rasberry goes 32 load average and rebooted itself

[eikowagenknecht]

Same here, on both a Raspi 4 and a Raspi 5 this addon creates a lot of CPU load, even when not actively used.

I have always only used the /config folder, so it should not be the / problem.

This is a typical load on my Raspi 5 after using it once and then leaving it alone for days.
Using it multiple times makes the problem worse (maybe multiple instances?).

Maybe related (or not), autocomplete and linter sometimes take a few minutes.

My "workaround" is to manually stop the addon after using it and then restart it as needed.

[metbril]

Upgrade from 5.17.1 to 5.17.2 made my cpu usage for the add on spike from 2% to 30%. I've downgraded.

[emufan]

I've downgraded.

How did you do it?
