My site hosted on webfaction started returning a 500 internal server error
this morning and it looks like it's choking on my routing. What's strange
is that it was all working (with no changes made) for quite a while prior
to this. My server log shows this at the start of the problem:

My routes.py file has these instructions:
default_application = 'blog' # ordinarily set in base routes.py
routes_app = ((r'/(?P<app>admin|blog|peergrades|paideia)\b.*', r'\g<app>'),
(r'(.*)', r'blog'),
(r'/?(.*)', r'blog'))
routes_in = (
# make sure you do not break admin
('/admin','/admin'),
('/admin/$anything','/admin/$anything'),
# make sure you do not break appadmin
('/$app/appadmin','/$app/appadmin'),
('/$app/appadmin/$anything','/$app/appadmin/$anything'),
)
routes_out = (
# make sure you do not break admin
('/admin','/admin'),
('/admin/$anything','/admin/$anything'),
# make sure you do not break appadmin
('/$app/appadmin','/$app/appadmin'),
('/$app/appadmin/$anything','/$app/appadmin/$anything'),
)
logging = 'debug'
Then I have an application specific routes.py file with these rules:
#!/usr/bin/python
# -*- coding: utf-8 -*-
# default_application, default_controller, default_function
# are used when the respective element is missing from the
# (possibly rewritten) incoming URL
routes_in = (
('\b?', '/blog/plugin_blog/index'),
('/', '/blog/plugin_blog/index'),
('/index', '/blog/plugin_blog/index'),
('/index.html', '/blog/plugin_blog/index'),
('/login', '/blog/default/user/login')
('/blog/default/index', '/blog/plugin_blog/index'),
('/articles/$anything', '/blog/plugin_blog/articles/$anything'),
('/classes/$anything', '/blog/plugin_blog/classes/$anything'),
('/new_post', '/blog/plugin_blog/new_post'),
('/edit_post/$anything', '/blog/plugin_blog/edit_post/$anything'),
('/all_posts', '/blog/plugin_blog/all_posts'),
('/new_doc', '/blog/plugin_blog/new_doc'),
# don't break download links
('/blog/default/download/$anything',
'/blog/default/download/$anything'),
# make sure you do not break admin
('/admin', '/admin'),
('/admin/$anything', '/admin/$anything'),
# make sure you do not break appadmin
('/blog/appadmin', '/blog/appadmin'),
('/blog/appadmin/$anything', '/blog/appadmin/$anything')
)
routes_out = (
('/blog/plugin_blog/index', '/'),
('/blog/plugin_blog/articles/$anything', '/articles/$anything'),
('/blog/plugin_blog/classes/$anything', '/classes/$anything'),
('/blog/plugin_blog/new_post', '/new_post'),
('/blog/plugin_blog/edit_post/$anything', '/edit_post/$anything'),
('/blog/plugin_blog/all_posts', '/all_posts'),
('/blog/plugin_blog/new_doc', '/new_doc'),
# don't break download links
('/blog/default/download/$anything',
'/blog/default/download/$anything'),
# make sure you do not break admin
('/admin', '/admin'),
('/admin/$anything', '/admin/$anything'),
# make sure you do not break appadmin
('/blog/appadmin', '/blog/appadmin'),
('/blog/appadmin/$anything', '/blog/appadmin/$anything')
)
Does anyone have any idea what would be causing the error? This is a
production site that has been running fine for about four weeks (1 week
with the routes.py set up more or less this way, 1 day with these specific
settings).
Thanks
