Hi, i am new to Passenger. I am having this error on a RoR app.

Passenger encountered the following error:

The application spawner server exited unexpectedly: Unexpected end-of-
file detected.

Exception class:
PhusionPassenger::Railz::ApplicationSpawner::Error

Thanks in advance for your help.

Did you figure out what was causing this? I'm seeing it show up on
one of my apps all of a sudden. Running rails 2.3.4. It was working
just a couple of days ago.

Thanks,
Trey

I just tried upgrading to 2.2.5, but I'm still getting this on one of
the rails sites on my review server. There are other rails sites on
this box using passenger which are even 2.3.4 as well, so it must be
something affecting this particular app. Does anyone know where I
should begin to look? Here's the full output from the passenger error
page:

Bah, nevermind.

I finally checked the main apache error log and discovered there was a
problem with one of my gems.

I think passenger should at least give an option to see more of the
stack trace that gets reported in apache's error log. Would have been
more helpful.
