mod_wsgi crashes

[micrology]

I have apache2 @2.2.27_0+preforkmpm, python27 @2.7.8_1 and mod_wsgi @4.2.7_0+python27 installed in Mac OS X 10.9.4. Enabling "LoadModule wsgi_module modules/mod_wsgi.so" results in a crash:

Commenting out the LoadModule line allows Apache to run, but of course without mod_wsgi.

Can you attach the complete crash report?

The crash report is now attached.

OK, so it's obviously a null pointer dereference. The loaded python library seems to be correct. I'll try to reproduce.

Works fine on my system. I have updated mod_wsgi to the latest version in r124538, please try and see if that helps.

Since the port doesn't have a maintainer in MacPorts you might want to request assistance upstream (port gohome mod_wsgi) or investigate further yourself.

Thanks for the latest version, but regrettably, it doesn't make a difference. I will seek help from the module author.

Solved! The trick is to ensure that once mod_wsgi has been included in your httpd.conf file, you stop the server (sudo apachectl stop) if it is running, and then start it (sudo apachectl start). Do not just use sudo apachectl graceful , as I did.
