BUG #: 1496 (SQLBUG_70)


When using a multi-threaded program to process multiple OLAP cube partitions in parallel, various errors may occur due to OLAP Repository lock synchronization problems. These messages may include but are not limited to "Invalid Pointer", "Internal Repository Lock" and "Unexpected Error".

With OLAP Services Service Pack 2, Microsoft has improved OLAP Repository lock synchronization to prevent these types of errors from occurring.


Microsoft has confirmed this to be a problem in SQL Server OLAP Services version 7.0. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server OLAP Services version 7.0. For information about how to download and install the latest SQL Server OLAP Services Service Pack, see the following Microsoft Web site:
