[Spacewalk-list] Fwd: Can't get clients to register... Internal Server Error

[Richard Highness]

Hello.

Just stood up a CentOS 6.4 box with Spacewalk 2.0.  Was able to get one
client registered, but all subsequent hosts can't get registered.

When I run rhnreg_ks from the client, this is what I see:

[root at bugs ~]# rhnreg_ks
--serverUrl=http://spiff.royalhighness.org/XMLRPC--activationkey=1-centos6-x86_64
-vvvv

On the server, I see this in /var/log/rhn/rhn_server_xmlrpc.log:

2013/10/17 08:34:29 -07:00 1713 192.168.100.24:

2013/10/17 08:34:30 -07:00 1712 192.168.100.24:

2013/10/17 08:34:30 -07:00 1718 192.168.100.24:
xmlrpc/registration.create_system("token = '1-centos6-x86_64'", '6',
'x86_64')

Is there something obvious that I'm missing?

Thanks for any help you can give me on this.
