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.

Description of problem:

While verifying https://bugzilla.redhat.com/show_bug.cgi?id=1477550, I run remote execution job on multiple host (more than 20 hosts using select all bulk action).

But after that found Hosts -> All hosts page is broken.

Version-Release number of selected component (if applicable):

Satellite 6.4 snap 11


How reproducible: always


Steps to Reproduce:
1. Create 25 content hosts in satellite (assuming per page entries 20)
2. Select all hosts
3. Click "Select all X hosts"
4. Select action > schedule remote job
5. Run remote execution job on all hosts
6. Navigate to Hosts -> all hosts page

Actual results:

Remote execution job will run on all hosts but after that all hosts page found broken showing error

Oops, we're sorry but something went wrong comparison of String with nil failed

and production.log showed
