Symptoms
Analysis Server may stop and then restart when you browse cube data if the underlying data source is SQL Server and the data access is performed by using the OLE DB provider for SQL Server. Therefore, cube browsing from the cube browser may fail.
Resolution
When the query that is generated by Analysis Manager is too large, the SQL Server provider returns success for the status of the query and NULL for the pointer. The NULL value for the pointer causes Analysis Services to stop and then restart.
