Memory Leak when using ng #17022
Description
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.
