Zend Framework Ändern SetEnv APPLICATION_ENV auf "Produktion" bewirkt, dass apache 500 error

Wenn ich APPLICATION_ENV auf "Produktion" und Neustart von apache bekomme ich einen 500 Fehler. Wenn es um die Entwicklung habe ich keine Probleme. Ich bin völlig angefressen. Irgendwelche Vorschläge? Config-Dateien sind unten

httpd-vhosts.conf

#
# Virtual Hosts
#
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
# Use name-based virtual hosting.
#
NameVirtualHost *:80
NameVirtualHost *:443
#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
<VirtualHost *:443>
