Kirk,
I checked our configuration with a phpinfo (). --enable-debug is there and
part of the configuration. I have checked the error logs again and here is
some more information:

This stuff is killing our server. Our current solution is to bounce apache
every 15 minutes. However if the traffic gets heavy, then all the memory
gets sucked up and a reboot is required. I would greatly appreciate any help
I could get on this matter as it is way beyond my skills.
