Okay. 'Internal Server Error' doesn't really tell me much. Can you post 
the java exceptions somewhere and link to them, or send them as an 
attachment?

'Core dump' in oracle doesn't really tell me much either except, whoah, 
sounds bad. :)

I'm wondering how you could have set things up for push-to-clients if 
you didn't know what OSAD was.... if you don't set up OSAD then 
Spacewalk is client pull only.

What steps did you follow up to this point??

I don't know.

I honestly hate to pick on you at this point (although you probably 
think I'm a real meaniehead by now anyway) it is all on the main 
documentation page on the Spacewalk wiki, OSAD docs also turn up if you 
search for 'OSAD' in the Spacewalk wiki search or if you search for 
'OSAD spacewalk' in yahoo or google. Anyhow, here is the documentation 
from there that talks about OSAD beyond how to set it up:

https://fedorahosted.org/spacewalk/wiki/HowToRhnpush

OSAD is also mentioned in the python architecture diagram here:

https://fedorahosted.org/spacewalk/wiki/PythonDocumentation

For reference, the main Spacewalk documentation page is here:

https://fedorahosted.org/spacewalk/wiki/UserDocs

'OSAD' is meaningless if you have no idea what it means, but the 
description of the doc on the User Docs page does make it clear. Maybe 
the User Docs page would be easier to read if the docs were split out by 
functionality, though. E.g., client configuration, 
kickstart/provisioning, etc etc.
