EMFILE error on Mac when running Meteor app

Question

I can get my meteor app to successfully build and start by running

meteor
=> Started proxy.
=> Started MongoDB.
=> Started your app.

=> App running at: http://localhost:3000/

However when I kill the app with Ctrl+C, I get the following stack dump:

^C
fs.js:439
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

I can't trace this error to a specific point in my code, since no where in this stack trace does it point to a line of code I have written.

How might I go fixing this problem?
