Moved from https://blogs.msdn.com/vijgang
You create a new User Profile Service Application and try browsing to the Manage link for the User Profile Service Application, this page might fail with the following error,
If you filter on the “User Profiles” category in the ULS Logs, you should see these errors:

This is an expected behaviour if the User Profile Synchronization Service is started on the SharePoint server hosting Central Administration. A recycle of IIS services is required to get this working. This is actually mentioned on the page that is displayed when starting the “User Profile Synchronization Services”.
