Okay, I think I found it.
Putting this in your WSGI config should fix it:
WSGIApplicationGroup %{GLOBAL}
More details here:
https://techknowhow.library.emory.edu/blogs/branker/2010/07/30/django-lxml-wsgi-and-python-sub-interpreter-magic
So, this should allow the ogcserver to play nicely within mod_wsgi with lxml
installed. If this fixes the hang for you then we can investigate more. If not,
then make sure you are only running one instance of the ogcserver within Apache.
