Unable to watch for file changes in this large workspace

[safisa]

Bug Description:

Hi,

I added a web application (react) to my workspace, once I ran npm install that added a large node_modules folder to my workspace (inside an inner folder), I started getting this notification warning on load:
Unable to watch for file changes in this large workspace. The information you see may not include recent file changes.
I see also this error in Theia log:
ERROR [nsfw-watcher: 839] NSFW service error on "<workspace>": [Error: Inotify limit reached]

I have added this exclusion to my workspace settings under files.watcherExclude: "**/node_modules/**": true
but this did not help. it seems it is being ignored...

Additional Information

• Operating System: Linux
• Theia Version: 1.40

Hi,
Any help on this issue? files.watcherExclude maybe not working correctly?

Thanks

As far as I'm aware, file watcher exclusion does not work in the file watching library we're using see also Axosoft/nsfw#54.
