What is the WSGIDaemonProcess directive set to that you should also have for
each?
If you are not already doing so, add to the WSGIDaemonProcess directive the
option:
display-name=%{GROUP}
You can then use 'ps auxwww' to see processes and the daemon process group
process will be labelled differently to 'httpd' and you can verify better that
it is the process with Trac running in them which is going out of control.
