Red Hat Knowledgebase

This error is most commonly received when you are trying to use activation keys to connect a system profile to Red Hat Network (RHN) but you have exhausted all available management entitlements.

You would need to purchase additional Management level entitlements if you wish to continue using activation keys. Generally you will not get this error when using the up2date --register command unless you have previously created an activation key and designated it as the universal default key on your account. If you previously used an activation key flagged as the universal default, you would need to update the status on that Activation Key before you could create new profiles using the up2date --register command.
