Hi again. I looked harder in the error_log in /var/log/httpd and see the following. Not sure what this is related to, but it could be significant:
python_init: Python version mismatch, expected '2.6.5', found '2.6.6'. This happens at regular intervals in the history of today for example. And right after it:
python_init: Python executable found '/usr/bin/python'.
Any suggestions what this means to the performance of my server?
