Environment
SUSE Manager 3
SUSE Manager 4
SUSE Manager 4.1
Situation
Many tasks in the SUSE Manager web UI throw a "Internal server error", such as when trying to delete a system from SUSE Manager. When checking the cobbler logs (in /var/log/cobbler directory), the following messages are logged:

Resolution
Verify the /etc/cobbler/settings file and should the following line exist:
redhat_management_server: "xmlrpc.rhn.redhat.com"
adjust it with the FQDN of the SUSE Manager Server (hostname):
redhat_management_server: "yoursusemanager.your_fqdn.domain"
After saving the file restart the services:
spacewalk-service restart
redhat_management_server: "xmlrpc.rhn.redhat.com"
adjust it with the FQDN of the SUSE Manager Server (hostname):
redhat_management_server: "yoursusemanager.your_fqdn.domain"
After saving the file restart the services:
spacewalk-service restart
Cause
1. The file was likely incorrectly modified / updated during the migration from SUSE Manager 2.1 to 3.0.
2. The FQDN of the host has not been used.
