I have a normal react setup, without CRA, which means I manually configured webpack and babel etc... I currently have 2 scripts which run webpack : package.json :

  "scripts": {
    "dev": "NODE_OPTIONS='--openssl-legacy-provider --max-old-space-size=8000' webpack --watch --config webpack.dev.js",
    "prod": "NODE_OPTIONS='--openssl-legacy-provider' webpack --config webpack.prod.js"
  },

when I run npm run prod, the issue does not happen and all the assets get compiled like normal. However, when i run npm run dev, after working for a while (less than an hour), the terminal kills webpack and shows the following:

I'm not sure what is happening here but I saw some recommendations to circumvent the issue by adding --max-old-space-size=8000 to the NODE_OPTIONS in the script.

However the issue persists. Any idea How to deal with it ?
