I have a VM instance of Ubuntu Server 10.04, running django with mod_wsgi. It was working fine, and then after doing an /etc/init.d/apache2 reload and /etc/init.d/apache2 restart, I get nothing but Internal 500 errors. I checked the logs, and when I hit the server, nothing it output. However when the server is restarted, I get the following, which as far as I can tell is not related to my problem.

EDIT: Just realized I have a custom logging file, not in the usual place. Here is what the real log file has been catching all this time:

  • What was changed recently on the server - eg why were you doing a reload/restart. Perhaps there is a misconfiguration, file permission issue, etc...

  • The only thing I changed was in my django files. I did change the urls.py file because I was seeing intermitent Internal 500 Errors that would disappear on refresh. But I tried undoing that change and it didn't help. It's also a bit unbelievable that logging is showing nothing wrong.

  • Just added a whole new set of log messages after realizing I had set up a non standard log file path.

The only thing I changed was in my django files. I did change the urls.py file

mod_wsgi (pid=1693): Exception occurred processing WSGI script '/srv/www/mysite.com/application/django.wsgi

Go back and take a look at what you changed and then confirm the error shown in your error log above. It should be obvious. Your changes created the error. Try restoring the django file you modified... eg urls.py

In your /etc/apache2/apache2.conf file you can turn your logging up and maybe catch the error. You should find a section like this:

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel warn

Change it to this and try and restart the server:

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel debug

  • Lots of things can make Apache go boing, I think we just need a little more info to help you on this one.
