If you dont see one, please bump the debug level in /etc/rhn/default/rhn_server.conf, restart apache and retry. Also make sure you have the latest rhn-client-tools rpms from spacewalk-0.6 repo. ~ Prad <blockquote type="cite"><div class="im"> Please suggest me how I can resolve this issue . Thanks in Advance .
