Hi,

There's a memory leak with ng, it keeps consuming memory despite memory increase, I've monitored and it has already consumed more than 17 GB of RAM! I think the problem is related to SASS because the program is stucked with .scss files but I'm not sure.

I've tested with NODE_OPTIONS=--max-old-space-size=17000 but also node --max_old_space_size=20000 node_modules/@angular/cli/bin/ng build --prod later, always the same issue even if I try with 8192 instead of 17000 or 20000.

I know, this memory problem has already been opened multiple times, like here #13734, but it seems to be a persistent issue

Terminal

ng serve
Your global Angular CLI version (9.0.2) is greater than your local
version (8.3.24). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

Can you try using Node v12.4.0+? There are some node versions that suffer from memory issues.

I've uninstalled node v13.8.0 and installed node v12.16.1

I have a war machine under my control and still can't control JavaScript related tools 🤣

@eau-de-la-seine, is there anyway that you can share your project so that we can take a look at this issue?, even privately.

I would have love to but I cannot send this company project. Anyway I've found a solution: remove the whole project and clone it again, now it works. This is still weird to me since the source code wasn't changed and even npm cache clean --force didn't work. Thanks for your time Alan :)
