Note: You may need to configure PassengerMinInstances 2 in /etc/httpd/conf.d/05-foreman-ssl.conf in order to have at least two processes that interfere each other.
Created redmine issue http://projects.theforeman.org/issues/15407 from this bug
Upstream bug component is WebUI
WORKAROUND: cat >>/etc/httpd/conf.d/passenger.conf <<EOPS # Allow only one Foreman and one Puppet Master process <IfModule mod_passenger.c> PassengerMaxPoolSize 2 </IfModule> EOPS This limits number of processes one each, this will slow down processing of requests tho.
Moving to POST since upstream bug http://projects.theforeman.org/issues/15407 has been closed

VERIFIED on satellite-6.2.5-1.0.el7sat.noarch I used the docker containers (with katello-agent trigerring registration to the satellite). with ~200 hosts registering pretty much at the same time and was unable to hit the issue. (for the previous version of satellite, this was replicable even with <10 containers).
