I started my first project with ember cli and I noticed that the live reload isn't working. When I start the development server, I get multiple error messages (see below). Changes to the code base are only available after a restart of the server.
$ ember server

Livereload server on port 35729

Any idea what could cause this issue? It is quite annoying to restart the server for every change. Thank you for your suggestions.
The error is essentially caused by FSEvents watching too many files. If you're using Sublime Text, try excluding node_modules/, tmp/, and dist/ from your project (add them to the folder_exclude_patterns array in your Sublime user preferences).
If you're not using Sublime, or if doing so doesn't fix the issue, try upgrading your version of Node and version of ember-cli to the latest versions, as well as installing watchman using brew install watchman if you have Homebrew installed/are on OS X (as the latest versions of ember-cli no longer rely on FSEvents.
