Hi Graham,
Firstly, thank you for responding so quickly and thanks for the great tip
(to just read the docs)! The debugging techniques and adjustments you
suggested have helped me narrow down the issue further (I think).
So, I am still experiencing the timeout, but I strongly believe that the
issue is not with Apache and mod_wsgi; rather the application (Django / my
code) communicating with the MySQL database. Remember, this problem only
occurs when "DEBUG = False" in my projects' settings file. When I run the
project with "DEBUG = True", the next entry in the log files refers to the
attempt Django makes to access the database for the first time to update /
retrieve the anonymous session.
