[Spacewalk-list] RHN Traceback emails from Spacewalk server after client upgrade

[faris at gmx.us]

Hi.
 After client upgrade and subsequent reboot I started to receive RHN Traceback emails from server regarding upgraded clients with the following error:

 ===
 While running 'get_server_capability': caught <class 'spacewalk.server.apacheRequest.UnknownXML'> : Invalid request received (method 'get_server_capability' doesn't have a class and function).
 Exception Handler Information
 Traceback (most recent call last):
File "/usr/lib/python2.6/site-packages/spacewalk/server/apacheRequest.py", line 120, in call_function
func = self.method_ref(method)
File "/usr/lib/python2.6/site-packages/spacewalk/server/apacheRequest.py", line 422, in method_ref
classname, funcname = string.split(method, '.', 1)
 UnknownXML: Invalid request received (method 'get_server_capability' doesn't have a class and function).
 ===
 What does it mean exactly and how to correct it?
