That all looks reasonable. I can only suggest that this point if you have a working ‘gdb’, is to following instructions in:
* http://modwsgi.readthedocs.io/en/develop/user-guides/debugging-techniques.html#debugging-crashes-with-gdb <http://modwsgi.readthedocs.io/en/develop/user-guides/debugging-techniques.html#debugging-crashes-with-gdb> to try and attach gdb to the daemon process and then fire the request and get a stack trace of all the threads when the process crashes.
