Topic: Passenger Crashing

We have a ror server using apache and passenger.

I enabled a second site on the server, a duplicate of the original but on a different domain. I made a new conf file for apache, rebuilt the httpd.conf and then restarted the server.

This causes passenger to crash

Phusion Passenger version 3.0.11
ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-linux]
Server version: Apache/2.2.22 (Unix)

Any ideas or similar experiences?
