  • Ticket #17658 – Description

    initial v2  
    1 After a very standard and minor release, our Apache/Nginx/Django/wsgi setup ceased to function with the only error "Premature end of script headers: django.wsgi" in the apache log.
     1After a very standard and minor release, our `Apache/Nginx/Django/wsgi` setup ceased to function with the only error "Premature end of script headers: django.wsgi" in the apache log.
    22There is no expat problem (checked with sample wsgi app with and without that module include). The server was working fine. The codebase was updated slightly and apache restarted when the horrors began. The codebase was rolled back and still the problem persists.
    33Below are my wsgi file, apache config and a dump from running wsgi under the debuger.
