Remote Extension host terminated unexpectedly 3 times within the last 5 minutes.

[JiaY-shi]

Is there an existing issue for this?

• I have searched the existing issues

OS/Web Information

• Web Browser: Chrome
• Local OS: macOS
• Remote OS: debian testing
• Remote Architecture:
• code-server --version: amd64

Steps to Reproduce

Expected

The extension function should work normally

Actual

Currently, when I open code-server, the extended functions cannot be used normally and it always prompts that it is closed. I mainly use git-related functions.

Does this bug reproduce in native VS Code?

This cannot be tested in native VS Code

Does this bug reproduce in GitHub Codespaces?

I did not test GitHub Codespaces

Are you accessing code-server over a secure context?

• I am using a secure context.

Does this happen without any extensions installed? It would be good to test in Codespaces as well, it seems more likely to be an upstream VS Code issue than a code-server issue.

@code-asher When I uninstalled all extensions, the problem still exists.

[code-asher]

Interesting, it might be coming from a built-in extension in that case. We upgraded VS Code yesterday to 1.98.0, once we get that out in a code-server release we should test to see if the problem remains (should be done today).

@code-asher In version v4.98.0-rc.1, had the same problem

update:it works fine after downgrading to v4.96.4

[code-asher]

Oh interesting that downgrading to 4.96.4 works. The only major thing that happened between those releases was updating VS Code, so it does seem likely the problem is in VS Code itself, or in one of the built-in extensions. 🤔

I see they fixed a similar issue (microsoft/vscode#242036) but supposedly it was fixed in 1.98.0, so I would have expected the RC to work if it was the same issue.

[afshawnlotfi]

Still getting same issue even after downgrading to 4.96.4

[JiaY-shi]

@code-asher The same problem still occurs when using the latest version (4.98.2), and the CPU usage is found to be very high during on-site debugging.

Update: The high CPU usage is caused by indexing. It has nothing to do with this issue.
