[Spacewalk-list] Error Downloading Packages From Channel Behind Proxy

[Wojtak, Greg (Superfly)]

I'm getting an error when I try to update packages from a certain channel on systems behind a spacewalk proxy.  I'm getting the following when updating/installing:

# yum update yum-rhn-plugin
Loaded plugins: downloadonly, fastestmirror, rhnplugin

I get this only for 1 or 2 different channels behind the proxy.  Others work fine.  All software channels work fine for all systems communicating directly to the spacewalk server, ie not behind a proxy.

Any ideas where I can begin to debug this?  This is spacewalk 1.8 on centos 6 64-bit postgres back end.
