Error - A required timer job for a User Profile Application or User Profile Application Proxy is missing
I started seeing this in Health Analyzer
This is a bug that doesn't seem to affect UPA in any way. The intent from MS was to add a new timer job to the UPA in the August 2011 CU (this farm is built to the Aug CU patch level). MS got it in there, got the health check for it, then for some reason pulled the timer job from the CU, but didn't pull the health check
This issue is now fixed and this fix is rolled into Dec 2011 CU.
