cname redirect stops working periodically?

I have added a cname redirect by doing the following:

1.) Logging into the domain cpanel
2.) Click on simple DNS editor
3.) Selected the domain I wanted to add the cname redirect to
4.) Added openid as the name and socialize.gigya.com as the cname
5.) Clicked add cname record

Then I logged into WHM and restarted DNS.

The redirect works for a period of time (about 30 minutes) then no longer works.

If I restart DNS it works again for a period of time then stops working.

What am I doing wrong?

Any help is greatly appreciated!
