Errors when using with sass-loader

[VioletFlare]

Hello,

I have a pretty large codebase to compile and I was trying sass-embedded.
When I am running webpack with the following config:

					{
						loader: 'sass-loader',
						options: {
							sassOptions: {
								sourceMap: true,
								includePaths: [path.resolve(__dirname, 'Develop', 'Styles'), path.resolve(__dirname, 'WebComponents')],
							},
							implementation: require('sass-embedded')
						}
					}

Dart errors with the following error:

> webpack --config webpack.configs.dev.js --watch

It looks like evenhandler_win.cc is a dart file.

Can you provide a clean reproduction of this, ideally only using the Sass embedded API without the WebPack loader around it?

Sorry, I cannot make a reproducible example using only sass-embedded api right now. However I have something that might aid in the reproduction of this case or which might serve as a temporary solution.

While I was running the webpack build using sass-embedded, the memory usage grew to 8 GB between the various node processes and dart executables running and got to a point where no memory was available. At some point I was running out of physical memory, my disk was nearly full (had nearly 250 MB left), after cleaning my disk I am not running into this issue anymore.

I forgot to mention I am using windows :)

So it seems as something related to Windows Virtual Memory management or Dart itself.

That sounds like it may be an issue with sass-loader spawning too many instances of sass-embedded concurrently. This should be fixed by webpack-contrib/sass-loader#1195, but if you're using a version of WebPack that includes that PR you might want to file an issue there explaining the problem.
