So there is no error actually being output from the server? It just straight
up hangs?

Without any error output, or trace, it's very hard to say. At this point I
wouldn't know what to point my finger at except for the local extensions of
the js runtime. Maybe try replacing therubyracer with another gem like
therubyrhino, run bundle update and see if you have any different, or at
least more verbose results.

So:

in ./Gemfile
remove: gem 'therubyracer'
insert: gem 'therubyrhino'

then from the shell:

> bundle update
