FIX: You receive an error message when you log on to or log off from a Commerce Server 2007 SP2 site

SYMPTOMS
You log on to or log off from a Microsoft Commerce Server 2007 Service Pack 2 (SP2) site. However, you intermittently receive an error message that resembles the following:
A duplicate value for unique key member <profile property> found while building indices for profile Contact. Check the underlying store for uniqueness of the property.
Notes
  • Values for "profile property" vary according to the UNIQUE key that is set in the profile definition. "GeneralInfo.Username" is an example of a "profile property" value.
  • You can use Profiles Schema Manager to specify a UNIQUE key. For more information about Profiles Schema Manager, refer to the "More information" section.

Additionally, an event that resembles the following is logged in the Application log:
Log Name:      ApplicationSource:        ASP.NET 2.0.50727.0Event ID:      1309Task Category: Web EventLevel:         WarningDescription:Event code: 3005 Event message: An unhandled exception has occurred.

CAUSE
This problem occurs because Commerce Server 2007 SP2 does not handle exceptions that occur when a duplicate value is found for a UNIQUE key in the profile cache.
