Error: EMFILE on OSX when requiring lots of files

When requiring 256 files from a single file on OSX browserify throws:

Error: EMFILE, open '/Users/karl/Sites/KVP/GuruFramework/package.json'

From Googling around it looks like this is caused by attempting to open too many files in parallel.

It looks like this could be solved by using the graceful-fs module to limit the number of files opened in parallel.

As a work around I have upped the file limit for my user by adding this to ~/.bash_profile

# Work around bug in browserify
ulimit -n 2560

I’m already using npm 3… And with modules I ment application entry points => bundles for browserify. The problem is that I’M creating multiple bundles at the same time. I need to implement some kind of scheduler which watches over it and limits it e.g. to 5 parallel browserify bundlings…
