Hi there,
I'm hoping someone can help me out here :-)
*Problem description:*
- When setting the Django settings option "DEBUG = False" (typically used
to switch to production settings) I get a "Gateway Timeout" from Apache.
When "DEBUG = True" everything works just fine!
- Apache error: *mod_wsgi Timeout when reading response headers from daemon
process.*
*Setup:*
- I have a vanilla install of Ubuntu16.04 with Apache 2.4. As per the
"mod_wsgi" documentation I am making use of the virtual environment to load
up the "mod_wsgi" environment into Apache.
- I have a Python virtual environment running where all of my required
Python libraries / modules are located (including "mod_wsgi"). All Python
libraries / modules are at the latest stable versions.
- I have only used the default package managers i.e.: apt and pipenv
respectively on this clean install.
- The Apache user / group "www-data" is the owner of the default
"/var/www/" directory.

Any ideas as to how I can isolate the what is causing the problem or point
me in the right direction before I go down the proverbial rabbit hole?
Thanks in advance.
