SYMPTOMS

In Microsoft SQL Server 2008 Analysis Services or in Microsoft SQL Server 2008 R2 Analysis Services, you run an UPDATE CUBE statement on a cube in a database. The UPDATE CUBE statement takes a long time to finish. At the same time, you run an ALTER command on the database. In this situation, the operation is blocked, and then the Analysis Services service stops responding. Additionally, you cannot create a new connection to the server unless you restart the Analysis Services service.

CAUSE

This issue occurs because the UPDATE CUBE statement requests a READ COMMIT lock on the database. When you run an ALTER command, the operation requests a WRITE COMMIT lock on the database. However, the ALTER command must wait for the UPDATE CUBE statement to release the READ COMMIT lock. Therefore, the UPDATE CUBE statement blocks the ALTER command and then blocks all additional requests.
