You have a running User Profile synchronization Service, configured with an Active Directory connection and in addition a Business Data Catalog (BDC or also known as Business Connectivity Service - BCS). You have the User profiles from the Active Dirtectory connection mapped to the Business Data Catalog by using the "Work Email" property to fill in additonal properties from the BDC into the Profile Import. After the first Full Import the Synchronization Service get stuck and in Application Event log you will find the following Error:
