Extension host terminated unexpectedly due to GitHub copilot

[edwardspresume]

Type: Bug

My extensions keep terminating. GitHub copilot seem to be the reason for the crash for myself and others. Disabling copilot stops the crashing for us, but we need a better solution

[fazofazaal]

I am having the same issue. This is so annoying

[tunayokumus]

same here. Issue started happening today. Didn't install any new extensions in the last days. Seems to be an OOM issue. Using WSL2 backend.

[VladSez]

Not sure, if this is relevant, but after I disabled Github Copilot extension, looks like the issue is gone (at least for the last couple of hours it's not crashing)

I am on WSL2

[ghana7989]

It is so frustrating that I have to reload just to expect a crash with in 5 mins or less.
please fix this ASAP

[nacmartin]

Not sure, if this is relevant, but after I disabled Github Copilot extension, looks like the issue is gone (at least for the last couple of hours it's not crashing)

I am on WSL2

Yes, I have done the same and the sun shines again.

[atomflunder]

Same here, thanks for the fix!

Thank you! This fixed it for me as well

[Ali-AlDhamen]

same here been having this issue for a week now, it's annoying

[starball5]

Related question on Stack Overflow: Extension host terminated unexpectedly 3 times within the last 5 minutes

[TeddyCr]

Same here. Having this issue for about a week. Quite unfortunate.

[wasied]

Same for me with Github Copilot. Quite annoying.

[deepak1556]

Can users provide the following 2 logs,

1. Open Developer: Toggle Developer Tools and attach the generated log when extension host terminates
2. Start the application following the steps at https://github.com/microsoft/vscode/wiki/Native-Crash-Issues#creating-a-crash-report and attach the generated crash logs if available.

[TeddyCr]

I get a log of things from the developer tool, unsure which one to share. Let me know if that one help

abstractExtensionService.ts:931 Extension host (LocalProcess) terminated unexpectedly. Code: 7, Signal: unknown

[Extension Host] (node:15816) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.
(Use `Code Helper (Plugin) --trace-deprecation ...` to show where the warning was created)

the 2) does not provide anything.

Looks like it does come from the copilot extension though, as soon as I re-enable it it the host terminates.

[deepak1556]

Code: 7 seems like an exit due to OOM, @TeddyCr can you launch the application with code --verbose and attach the logs once extension host terminates.

[TeddyCr]

🤔 I am not sure what to share there. I get a big block of code from there /$HOME/.vscode/extensions/github.copilot-1.77.9225/dist/extension.js:8

[deepak1556]

It would be great if you can share all the logs printed to the terminal, if not can you check for a line that has the following crashed with code 7 and reason .... I am mainly looking to confirm the value of reason.

[bpasero]

👋 , since we just merged a lot of issues into this one as duplicate: has anyone been able to figure out a pattern that reproduces this issue reliably? We in our team all use Copilot on the same version and so far have not yet hit this issue.

Is it just using Copilot over some time in the editor when it randomly happens? Are there any settings configured around Copilot or editor suggest that might have an impact?

[Gerrnperl]

@bpasero
For me the extension host always terminates when I do a git commit via vscode. When I disable Github Copilot (or just for 'git-commit'), the crash doesn't happen anymore.

And there will be a small probability of termination at other times

When Copilot tries to autocomplete when I enter a commit message, the extension host terminates

VS Code Version: 1.76.1 (Commit: 5e805b7 , Date: 2023-03-08T16:31:31.010Z)

OS: x86_64 Linux 5.19.0-35-generic, Ubuntu 22.10 kinetic

[yegor-ch]

The same issue. It's related to a new version of the Copilot.
Try to downgrade the Copilot version to 1.76.9071

[isidorn]

Can anyone reproduce this issue with the previous Copilot version 1.76.9071? You can change extension version by opening the Extensions viewlet, right click on Copilot > Install Another Version.

Also sharing exact steps like @Gerrnperl is extremely helpful for us!

[bpasero]

@Gerrnperl thats a very nice small repro, which unfortunately I cannot reproduce. Curious, when you observe the memory used by "utility process" when the "Process Explorer" is opened (from "Help" menu), does that memory suddenly go to a very large value and then restart the process?

@isidorn
For me, the previous version of Copilot didn't cause this issue.

[TeddyCr]

Same for me 1.76.9071 works as expected. As soon as I upgrade to the latest version the extension host eventually crashes within a few minutes.

@bpasero

"utility process" took up about 400 MB at the time of the crash
I'm not sure if this is "unusually large", but with Copilot disabled, the utility process memory usage fluctuates between 100 MB and 350 MB (and sometimes rarely exceed 400 MB)

[bpasero]

@Gerrnperl thanks, could you quit VS Code, run code --verbose, reproduce the issue and then send the logs as Zip from that session (e-mail is fine, its viewable on https://github.com/bpasero). You can find the logs folder from this command:

And it would be the most recent folder entry (every session gets their own folder).

[Baz00k]

@bpasero I have reproduced the bug with --verbose flag and sent you zip by email

[abgoswam]

for folks who saw this issue on Copilot version 1.77.* (or above), could you re-enable the latest version and check if the issue still persists ?

• if the issue still persists, would it be possible to send the logs using the steps mentioned by @bpasero above

[isidorn]

+1 for @abgoswam comment from above. We have identified a potential experiment that was causing the problem, and we have turned it off just now. We now believe the issue is fixed. Thus - please try again and let us know if you still see the problem. Thanks all!

[a-r-j]

Thanks for the fix! So far so good for me.

[isidorn]

@a-r-j thanks for verifying.

I am going ahead and closing this issue. If anybody is still seeing Extension Host crashes with Copilot do let us know and we will reopen this issue. Thank you all for your help!

[myagizmaktav]

my problem was fixed. above 1.77.97

[verveguy]

@isidorn I'm still seeing it on a fresh install of latest Copilot extension. 1.78.9758

[isidorn]

@verveguy do F1 > extension bisect. Most likely another extension is causing it, or it is another Copilot issue. In which case - fell free to open a new issue. Thanks

[ozjuly19]

I also had this issue mine was a complete breakdown of my WSL2 install due to windows refusing to mount the virtual disk anymore. I have no solution at this time but this is possibly caused by WSL2.
