itjackiewong,
I posted bug 3828 so I have some direct knowledge about this. If you read in the bug report, you will find that I said I pressed the Reconfigure button after the yum update as per procedure, well I did. My mistake was that the process must not have finished before I got off the yum update page, so, my advice to you is to go to a command line as root and type:
signal-event post-upgrade
WAIT until it completes and the prompt returns. Then type
signal-event reboot
and the server should reboot. Let the system update on the reboot and all should be fine.
