In that case, I bet this is your yum-updatesd daemon interfering. Try this:

# service yum-updatesd stop

And then:

# chkconfig yum-updatesd off

Basically, you can't have two instances of Yum running at the same time. 
Up to CentOS 5.2, yum-updatesd defaulted to on, but I understand since 
5.3 it defaults to off.
