Software updater hangs

I am running RHEL 6.6 on an HP Proliant DL380 G8 server. The system is subscribed to the Red Hat Subscription manager to get automatic updates. Lately I have noticed that when I apply updates, the updater does not finish completely and it actually hangs toward the end of the package installation. I have to force it to close since it does not finish on its own.
Has anyone encountered this problem and how did you fix it? I did not have this problem until recently and the updates have always been installed and the updater would indicate as such without fail.

Thanks,
Michael Sutherland
