NodeJS + ExpressJS wait 2 minutes before sending .js files

I'm having problems loading .js files with my NodeJS project. In this project I'm currently running NodeJS 0.6.15 and Express 2.5.6.

The problem is that when I make a request for a .js file, it takes exactly 2 minutes.

Any idea?!

It's quite strange because it has been working for a long time, and now without changing anything it gets this error. After 2 minutes it returns the files perfectly.

Most likely, you are not calling response.end(), so the connection times out in about 2 minutes (typical of HTTP/1.1), gets flushed and closed, and you get your content back in the browser.
