lsp-eslint easily trigger "Too many open files" error on macos

1. lsp client returns (lsp-session-folders (lsp-session)) as workspaceFolders to lsp-eslint
2. lsp-eslint tell lsp client to watch all the folders
3. which makes emacs process exceeds the default max file descriptors per proc

1. is lsp session supposed to be persist?
2. is the above description the supposed way?
