Emacs: Too many open files

Source: Gotcha: Emacs on Mac OS: Too Many Files Open
Got this error while trying to save a file in Emacs lately. Seems to be related to lsp-mode, which I'm using with Elixir.

Solution:

M-x file-notify-rm-all-watches

Before:

❯ ps auxww|grep Emacs
jerome            1697   0.0  1.0 37216772 162408   ??  S    16Feb23  21:04.84 /Applications/Emacs.app/Contents/MacOS/Emacs
❯ lsof -p 1697 | wc -l
    1640

After:

❯ lsof -p 1697 | wc -l
    664
