Why doesn't osad failover to additional servers listed in "serverURL" when enable_failover is set to 1?

Solution In Progress - Updated -

Issue

  • I configured multiple Satellite Proxy servers in a RHEL client:

    # grep serverURL= /etc/sysconfig/rhn/up2date
serverURL=https://proxy1.example.com/XMLRPC;https://proxy2.example.com/XMLRPC;https://proxy3.example.com/XMLRPC;

  • I enabled failover for osad:

    # grep -A1 failover /etc/sysconfig/rhn/osad.conf
# Turn the enable_failover option to 1 if you want the connections
# to try Satellite's jabberd if Proxy's is not available.
enable_failover = 1

  • Why does osad try to connect to the first server listed in serverURL only?

  • Why doesn't osad try to connect to any of the other servers listed in serverURL in /etc/sysconfig/rhn/up2date when the first server is unavailable?

Environment

  • Red Hat Satellite 5.7.
  • Red Hat Satellite Proxy 5.7.
  • Red Hat Enteprise Linux 6 with osad enabled and configured with option enable_failover = 1.
