Explanation: There are two or more sampling sessions with the same target database, possibly because there are two or more different ODBC DSNs or connection strings that point to the same target database.

When you upgrade Foxhound to a new build, each sampling session tries to update the three Foxhound properties procedures on its target database, and only one attempt will work for each target.

You will see three or more error messages along with the three successful "Info:" exceptions:
