KB2971611 - FIX: Memory leak occurs during Process Update on a dimension in SSAS 2008 R2

Symptoms

Assume that you have applied Cumulative Update 7 (CU7) or later versions for Microsoft SQL Server 2008 R2 Service Pack 2 (SP2). When you perform a Process Update operation on a dimension in SQL Server Analysis Services (SSAS), the Memory Usage KB and Cleaner Memory non-shrinkable KB counters keep increasing and not being released. In this situation, memory leak occurs.

Cause

The issue occurs because there is a regression in SQL Server 2008 R2 SP2 CU7 which causes memory leak in Process Update.

Each new cumulative update for SQL Server contains all the hotfixes and all the security fixes that were included with the previous cumulative update. Check out the latest cumulative updates for SQL Server:
