CAU set up for self updating, but it doesn't execute

Hi All,

I've setup CAU self updating on several clusters in my environment and for the most part it works great.  I have one cluster though that I have enabled self updating on, but it refuses to execute on it's schedule.  I can run CAU manually and it works fine, it just refuses to run on a schedule. 

I don't see any errors in the "Analyze cluster update readiness" tool.  I don't see any errors in the event logs.  It's just like the event never triggers/fires.  Like I said, manually it works fine, but I need it to run in an automated state at 3:00am. 

Any thoughts on where i should start looking? 

Thanks,
Jerrett
