Fixed In Version: openstack-puppet-modules-8.1.13-6.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.

I copied the doctext from the parent bug.
Comment 8 Radomir Dopieralski 2017-09-22 15:35:32 UTC 
I installed the latest puddle with openstack-puppet-modules-8.1.13-6.el7ost.noarch

I verified that Horizon is accessible, and that /etc/httpd/conf.d/15-horizon_vhost.conf contains the line WSGIApplicationGroup %{GLOBAL}.
