To avoid concurrency issues and deadlocks on Microsoft SQL Server 2008, MDM Server requires that you activate read-committed isolation using row versioning by running the following statement on the MDM databases:

ALTER DATABASE <database name>
  SET READ_COMMITTED_SNAPSHOT ON
  WITH ROLLBACK IMMEDIATE;
