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.
