RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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.

Additional info:
Comment 2 Sudhir Menon 2017-09-01 13:54:57 UTC 
Had tried the option 'Delete Server' which caused this issue.
Comment 3 Petr Vobornik 2017-09-01 21:04:22 UTC 
So this happens when you delete the last server in topology from Web UI, but Web UI is still up and running and API as well?
Comment 4 Pavel Vomacka 2017-09-04 08:28:33 UTC 
After 'Server Del' on a standalone server: WebUI files will be still loaded in the browser. HTTPD server is still running and several API calls still work (i.e. user_find/user_show/json_metadata, etc). But API call 'config-show' fails and therefore the whole WebUI fails and is not usable.
Comment 5 Petr Vobornik 2017-09-22 18:17:01 UTC 
This is a situation where server is doomed anyway so there is no point to fix it.
