2.4.0 causes OOM errors in docker running node 12.18.2

[radoi90]

• Operating System: Linux Alpine
• Node Version: 12.18.2
• NPM Version:
• webpack Version: 4.44.2
• eslint-webpack-plugin Version: 2.4.0

The project uses an ejected create-react-app base.

Expected Behavior

Production build to pass.

Actual Behavior

Production build throws OOM sigkill error.

Code

new ESLintPlugin({
  // Plugin options
  extensions: ['js', 'mjs', 'jsx', 'ts', 'tsx'],
  formatter: require.resolve('react-dev-utils/eslintFormatter'),
  eslintPath: require.resolve('eslint'),
  context: paths.appSrc,
  cache: true,
  // ESLint class options
  cwd: paths.appPath,
  resolvePluginsRelativeTo: __dirname,
  baseConfig: {
    extends: [require.resolve('eslint-config-react-app/base')],
    rules: {
      ...(!hasJsxRuntime && {
        'react/react-in-jsx-scope': 'error',
      }),
    },
  },
}),

Running into the same problem when using the node:14.15.1-alpine image too.

Setting threads: false seems to solve the issue.

Please create reproducible test repo, we can't fix something somewhere

[alexander-akait]

or provide OOM stack as minimum

[michaelangeliu]

As a temp fix, you can try increasing the amount of memory allocated to the node process in the build:
NODE_OPTIONS=--max_old_space_size=4096

Should be addressed in #55

Setting threads: false seems to solve the issue.

Can you tell me the file and the file path where to set this?

@Jayaramstarr the settings is in webpack-config regarding eslint you need to override it. Either using library like react-app-rewired or by ejecting it
