[Python-modules-team] Bug#758035: Truncated or oversized response headers received from daemon process

[Grégoire Bellon-Gervais]

Same problem here using RatticDB under Debian 8 :

root at www:/usr/local/RatticWeb/ratticweb# dpkg -l|grep apach
ii  apache2                        2.4.10-10                   amd64        Apache HTTP Server
ii  apache2-bin                    2.4.10-10                   amd64        Apache HTTP Server (modules and other binary files)
ii  apache2-data                   2.4.10-10                   all          Apache HTTP Server (common files)
ii  apache2-utils                  2.4.10-10                   amd64        Apache HTTP Server (utility programs for web servers)
ii  libapache2-mod-wsgi            4.3.0-1                     amd64        Python WSGI adapter module for Apache

And apache error log output :
