Rack application could not be started

[garrettlancaster]

It seems that I sometimes get this message, and other times it starts up fine. Any ideas would be appreciated.

I'm running on nginx and passenger, and have faye running on 4443 in my routes file.

Error message:
no acceptor

Exception class:
RuntimeError

That's pretty weird. Are you sure that you don't have two processes running at the same time?

I'm using capistrano, so maybe there is something in the way it deploys? I have also noticed that when I get the error, if I just leave it and come back after a while, it works fine...very odd behavior.

So it definitely sounds like it's a problem with access to the port. If you're using nginx then try switching to using unix sockets instead?
