Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

I am able to randomly reproduce on my own box, takes hours to hit with about 100 clients registering.
Comment 1 Lukas Zapletal 2016-06-10 12:44:43 UTC 
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.
Comment 5 Justin Sherrill 2016-06-14 12:45:54 UTC 
Created redmine issue http://projects.theforeman.org/issues/15407 from this bug
Comment 6 Bryan Kearney 2016-06-14 14:17:22 UTC 
Upstream bug component is WebUI
Comment 7 Lukas Zapletal 2016-06-20 12:32:54 UTC 
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.

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).
