Ok, I've found the root cause:
http://hackingredhat.com/index.php?title=Changes_in_Red_Hat_Network_%28RHN%29_that_Affect_Yum_and_Up2date_Downloads_in_Red_Hat_Enterprise_Linux_4.8_and_5.4

Adding up below entries to /etc/hosts solve my problem,
---------
173.222.132.218 content-xmlrpc.rhn.redhat.com
118.214.122.169 content-web.rhn.redhat.com
173.222.132.217 content-satellite.rhn.redhat.com
