A script containing two system calls: setting the OMEGA_CONFIG_FILE 
variable and calling the omega executable.

The only visible effect of the patch was the addition of "Content-Type: 
text/html" to the error message :)

The problem has been solved: apache doesn't seem to use the open file 
limit for its user as set in /etc/security/limits.conf. Running ulimit 
-n 2048 (or any other sufficient number) in the script starting apache 
did the trick.

I am somewhat confused about the error message though because it doesn't 
state "Too many open files" as it did before I changed the open file 
limit in limits.conf.

Thanks for the help!
