Suddenly this afternoon I started getting these error messages on several
spacewalk clients:
There was an error communicating with RHN.
RHN Satellite or RHN Classic support will be disabled.
Error communicating with server. The message was:
Error Message:
Please run rhn_register as root on this client
Error Class Code: 9
Error Class Info: Invalid System Credentials.

When I look on the spacewalk server I see the following types of errors in

These are all clients that have been successfully connecting to spacewalk for
some time. No changes have been made to the spacewalk configuration other
than adding new clients. Today I found a duplicate name and deleted the older
of the duplicates.
I did have 5 spacewalk Proxy Servers registered. It appears that somehow all
of my spacewalk proxy servers have been un-registered from the master. How do
I discover when and by whom these might have become unregistered?
