Problem/Motivation

After last update studio code server goes cpu of my raspberry at 36 load average and cause a force reboot of entire raspberry

Other problem is the port used for the new version is 1627 the same as Google Drive backup. And Google drive backup doesnt start (even if a ichange the port used)

I get this issue too. Whenever I launch vscode from the interface the CPU usage jumps up (and never comes down). If I launch another time it jumps again, until the instance becomes totally unresponsive and I have to hard reboot.

The problem for me started on Oct 10 after installing HAOS Core 10.1

I have experience CPU anywhere from 0 to as high as 94% (X64) sustained on the Add-on CPU usage.

I am seeing the same thing. I've shut down the addon for now.

I experienced the same issue with the VSC installation after the latest HA update. I resolved it by updating all YAML files to the new syntax introduced in the recent HA update.

Once I corrected the code and VSC no longer showed any syntax errors, the problem disappeared.

In my case, I noticed a correlation between the number of errors in the files and CPU usage. After fixing the issues in the automation.yaml file (which had over 30 errors), CPU usage dropped from 8% to 4%. Once I resolved the errors in the rest of my files, the load returned to the original 0.2%.

Platform: X86 native on an i5 NUC

Improved YAML syntax for automations
Recently, we renamed service to action in the Home Assistant UI and YAML. This was done with the goal of making the syntax more natural, allowing it to be easier to grasp and read. We want to continue this work to improve the YAML syntax, this time focusing on automations, and we’ve made the following changes,

The top-level trigger key is now triggers (plural)
The top-level condition key is now conditions (plural)
The top-level action key is now actions (plural)
The platform key of a trigger definition is now trigger

The result of all this is that YAML automation syntax now has triggers with multiple trigger definitions, conditions with multiple condition definitions, and actions with multiple action definitions.

I'm not sure it's linked in my case. I had no file open, so (I assume) no syntax checking going on. I did manually fix my automations.yaml file, just to see, and I'm still getting high cpu usage even after closing VS Code.

I'm not even sure the syntax checking kicks on, if I hover a property in the yaml, it just says "Loading..." and I never see any error of any kind.

There hasn't been any activity on this issue recently, so we clean up some of the older and inactive issues.
Please make sure to update to the latest version and check if that solves the issue. Let us know if that works for you by leaving a comment 👍
This issue has now been marked as stale and will be closed if no further activity occurs. Thanks!

Still happening on my install. My CPU usage goes from 1% to 8% with this thing running.

[emufan]

Same here. As I updated from 2024.6 to .11 and in parallel HAOS and add-ons as well, I don't know, from where it is coming, but it is more than bad. The addon takes now more than more memory, never releases it back, add even more on re-opening it,

... Only add-on restart brings the memory back. The whole system gets otherwise more and more unresponsive, most probably because of memory swapping, etc.

Here a start of the VSC UI. 40%. And Core (blue) and Supervisor (green) got swapped to disk I think. Orange is total up to over 95% what is odfc not healthy for the stability.

I have already deleted the addon and re-installed from scratch. Same behavior.

Andy chance to get help here? See only unmaintained issues regarding this severe problem.

Noticed mem use on my 4GB Pi5 rising sharply since yesterday and tracked it down to the VSCode addon which in Glances went from using ~75MB to peak at ~596MB before I uninstalled it and it went to zero. Reinstalled it and straight back up to ~425MB and climbing before I uninstalled it again. Also was getting unsecure access type messages when I opened it in WebUI. CPU use up to 18% as well.

[Lurker00]

I confirm that I have to restart VSC after every use of it, because it takes up to aroung 1GB of additional RAM and causes high CPU usage. Restart of VSC drops RAM/CPU back to normal until the next use.

But my Google Drive backup runs correctly.

Another observation is: restart of HA does not reclaim RAM used by VSC, but subsequent restart of VSC does. It means, VSC does not handle HA shutdown event to free resources.
