"glob error" code: 'EMFILE', I think due to a very large dependency tree

[rjmunro]

I have a project that installs a lot of dependencies and sub-dependencies (I'm not sure if this is an accurate measure, but find node_modules -name package.json | wc -l returns 2909). When I run node ./node_modules/.bin/lockdown-relock, I get a lot of output like:

glob error { [Error: EMFILE, readdir '/Users/rjmunro/ultimate-player/node_modules/protractor/node_modules/request/node_modules/hawk/node_modules/hoek']
  errno: 20,
  code: 'EMFILE',
  path: '/Users/rjmunro/ultimate-player/node_modules/protractor/node_modules/request/node_modules/hawk/node_modules/hoek' }

(EMFILE is related to having too many files open, which is why I suspect the large dependency tree is the issue here. I found some stuff about it here http://stackoverflow.com/questions/8965606/node-and-error-emfile-too-many-open-files)

Hi @rjmunro, my team has run into this in the past with command line tools that attempt to have a large number of files open concurrently, e.g. browserify.

It could be that your shell is limiting the number of resources you can have available at any given time. Would you mind reporting back what the ulimit command returns in your shell, and if adding ulimit -n unlimited to your shell profile (for example, .bashrc or .bash_profile) resolves the problem for you?
