VS Code crashes on launching a nodejs debugger

[jshwek]

Type: Bug

Whenever I launch the debugger, about 7 out of 10 times it crashes. After it crashes, I cannot stop or restart the debugger (I've also tried terminating individual processes in CALL STACK).

I've tried the extension bisect and got the result saying that the issue could be likely VS Code and not an extension.

Below is what comes up in the Developer Tools console: Extension Host localProcessExtensionHost.ts:283 <--- Last few GCs --->[62724:00004C9400320000] 233900 ms: Mark-Compact (reduce) 3497.4 (3561.3) -> 3442.2 (3473.4) MB, 75.3 / 0.0 ms (average mu = 0.955, current mu = 0.839) last resort; GC in old space requested[62724:00004C9400320000] 233978 ms: Mark-Compact (reduce) 3442.2 (3473.4) -> 3441.9 (3462.9) MB, 77.8 / 0.0 ms (average mu = 0.882, current mu = 0.000) last resort; GC in old space requested<--- JS stacktrace --->[62724:0525/141036.968:ERROR:node_bindings.cc(164)] Fatal error in V8: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory abstractExtensionService.ts:637 Extension host (LocalProcess) terminated unexpectedly.

This only happens for a specific (Node.js) project. I've never seen it crash for any other projects.

[roblourens]

Can you try to grab a trace?

/jsDebugLogs

[vscodenpa]

Please collect trace logs using the following instructions:

If you're able to, add "trace": true to your launch.json and reproduce the issue. The location of the log file on your disk will be written to the Debug Console. Share that with us.

⚠️ This log file will not contain source code, but will contain file paths. You can drop it into https://microsoft.github.io/vscode-pwa-analyzer/index.html to see what it contains. If you'd rather not share the log publicly, you can email it to connor@xbox.com

[jshwek]

Please see attached, many thanks in advance. vscode-debugadapter-040ce276.json.gz

[connor4312]

Thanks for the logs. They look mostly normal, but something suspicious I see is that the debugger is trying to parse sourcemaps from a bunch of non-sourcemap files in public/libs, such as public\libs\animate-on-scroll\animate-on-scroll.js. I suspect the crash might be related to some of the weirdness it's running into in that folder, but I'm not sure. The stacktrace reported in the debug console is unfortunately not very useful 😞

Are you able to share all or part of your project with me? At minimum, a .zip of the public/libs folder would be useful for me to try to reproduce if my hypothesis is correct.

[jshwek]

Hi @connor4312 and thanks for the update.

I'm using an admin template for this project that can be found here

See below for the zipped /dist folder which contains all the css, js, libs and fonts (and which I used). dist.zip

Please let me know if there's anything else I can provide and thanks again!

[jshwek]

Hi just checking if there's anything else you need?

[thisiswhereitype]

I am getting this error code on start which I initally reported here but now see this when running C:\Users\Joe> code --disable-extensions ~although adding --verbose appears to suppress the issue~ but only for a bit.

When running with extensions and not immediately crashing I noticed:

1. Opening extensions view triggered this instantly twice.

Hey @connor4312, this issue might need further attention.

@jshwek, you can help us out by closing this issue if the problem no longer exists, or adding more information.

[connor4312]

Unfortunately I haven't been able to trigger the crash in those files 😕 and so far I haven't had any other reports of such a crash, so I don't have a lot to go on. Any additional you can provide / a full repo would be helpful. You can also make a private repo and invite me to it if you aren't comfortable publishing something publicly.

[jshwek]

It actually hasn't happened to me in some time.

I'm guessing that an update went up that fixed my issue either directly or indirectly.
