Hi! I have a problem that seems to look a bit like these, however I find it 
very easy to fingerpoint at mod_wsgi:

I have a lot of different virtual hosts, but sometimes I get an error 
message on a port 80 host that can *only* be caused by a mix up with a port 
443 host running an entirely different server name. The error looks like 
this:

/var/log/apache2/error.www_host.com.log.1:[Sat Jun 23 18:37:07 2012] 
[error] [client 123.123.123.123] ImportError: Could not import settings 
'settings_alternative' (Is it on sys.path?): No module named 
settings_alternative

Now, the only wsgi script file that I have configured to load django with a 
settings module called "settings_alternative" is the script running on the 
443 host. But randomly I get the above error on a port 80 host. Logically, 
this can only be achieved by loading the wrong WSGI script in the correct 
path.

The error has been persistent for weeks, but sometimes it doesn't show up 
during hundreds of requests, making it very difficult to debug.

I'm currently running mod_wsgi 2.8 on Ubuntu Lucid, so the first thing I'll 
do is try to upgrade to mod_wsgi 3.X and report back if the problem has 
gone or not.
