Yum problems

Is any one else having problems this morning with Yum? We've had multiple servers who have started reporting many duplicate security patches. The duplicates appear to be from the rhel-7-server-optional-rpms/. Which, if we remove the repo, allows yum check-update to succeed.

Update notice RHBA-2014:0722 (from rhel-7-server-rpms) is broken, or a bad duplicate, skipping.
You should report this problem to the owner of the rhel-7-server-rpms repository.
If you are the owner, consider re-running the same command with --verbose to see the exact data that caused the conflict.

And multiple duplicates.

Have tried yum clean all, rm -rf /var/cache/yum, to no avail. Unsubscribing from the optional repo does fix it though.
