Fixed In Version: python-django-horizon-8.0.1-16.el7ost
Doc Type: Bug Fix
Doc Text:
Previously, some binary Python modules used by Horizon were compiled with a flag that requires them to use the simplified GIL state API. Since mod_wsgi uses sub-interpreters and the simplified GIL state API is not reentrant, it results in the mod_wsgi locking up. Consequently the dashboard is unavailable. With this update, the mod_wsgi configuration was changed, forcing mod_wsgi to use the main interpreter instead of sub-interpreters. As a result, mod_wsgi works correctly.

Comment 1 Radomir Dopieralski 2017-09-22 23:19:16 UTC 
Installed OSP8 with openstack-puppet-modules-7.1.5-7.el7ost from brew. Verified that it works and that the /etc/httpd/conf.d/15-horizon_vhost.conf file contains the line WSGIApplicationGroup %{GLOBAL}.
