Can you put together a repro repository for this.

[cortopy]

I'm experiencing same issue in an angular/cli 4.2.1 project. No ionic. It's been like this for days now.

After this many errors like Connection to server is erroring. Shutting down server.

[chuckjaz]

I would appreciate a repro for any of these cases.

[Anton-Nikishkin]

Just create new app and open it in VScode. Open any .ts file in src/app folder and wait...
After 2-3min (background work) the output window display an error:

[Manusan42]

Any news on this? Seems critical, for me the plugin cannot be used at all, just getting the FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory if the plugin is active and an angular project is open. I'm using the latest angular version 4.2.6 and cli 1.2.0.

[ianchi]

I have the same problem, when enabling this extension a code process eats the processor and goes up in memory usage until it hits about 1.5GB and crashes.
Excluding node_modules is a workaround (as noted in #104), but is there a way to exclude it from this extension, but not from the file explorer? There should be a specific option for this. (like there is a separate exclude setting for search).
Could it be that the version of @angular/language-service used by this extension is not up to date?

I'm using v0.1.4 and VSCode Linux 1.14 (and also happened in 1.13), with Angular 4.2.6 in the project.

[chuckjaz]

@ianchi Can you create a repository and steps that I can use to reproduce this?

[imesper]

@chuckjaz @Anton-Nikishkin already posted a way to reproduce it.

[chuckjaz]

@imesper That didn't reproduce it for me.

[ianchi]

I can reproduce it creating an empty project with:

ng new sample
cd sample
npm install

Then open code and wait about a minute. As stated, processor goes up and also memory, when the process gets arround 1.5gb it crashes with the following error in the Angular Language Services output panel:

It is interesting to note in the first row that it was scanning files inside the node_modules folder when this happened.

[derTuca]

@chuckjaz Just creating a new project using the Angular CLI reproduces the issue on my machine as well, but I have found out that it's a Windows-specific issue. macOS and Linux are working fine (for me at least).

[imesper]

Mine is Linux / Angular-Cli / Typescript 2.4.1.

[passenger6]

@chuckjaz To reproduce this problem you need to install this extension (IntelliSense for CSS class names): https://marketplace.visualstudio.com/items?itemName=Zignd.html-css-class-completion

If you disable this extension, Angular Language Service will works fine again.

[ianchi]

@chuckjaz I confirm I get the same behavior as @passenger6 .
If I delete node_modules from the excluded folders I get a new crash, but if I also disable IntelliSense for CSS extension everything works just fine, and memory never goes above 180mb.

[ianchi]

PS: updating to the new v1.8.0 of IntelliSense for Css class names doesn't solve the issue.

[derTuca]

Can also confirm the same behavior as @passenger6 and @ianchi.
