Passenger Error: [ASYNC BUG] thread_timer: select

I recently installed Rails on a cpanel machine using this guide: http://www.cpanel.net/blog/cpanel-whm-admins/2011/07/installing-mod-rails-and-rails-309-on-a-cpanel-machine.html

When I try and navigate to my app, I receive this error from Passenger:

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

Digging into Apache's error logs, the only error I can find related to this is:

[ASYNC BUG] thread_timer: select

I was wondering if anyone could help me figure out what is causing this? I've scoured the internet but haven't been able to come up with much :(

Passenger 3.0.10 has a fix for this problem. It will be released soon according to Hongli Lai (http://code.google.com/p/phusion-passenger/issues/detail?id=714). You can get the fix now by installing directly from the passenger github repository (https://github.com/FooBarWidget/passenger).

I just ran into this too. The current Ruby trunk appears to be incompatible with Passenger; you'll have to downgrade to 1.9.2.
