Microsoft SQL Server 2012 SP1 Cumulative Update 7

Microsoft has released SQL Server 2012 Service Pack 1 Cumulative Update 7, which is Build 11.0.3393.0. This CU has 47 fixes in the public hotfix list, a number of which seem to be quite significant for performance and stability.

Here are fourteen database engine-related fixes that are in SQL Server 2012 SP1 CU7:

FIX: Access violation when you trace an RPC event class by using SQL profiler or XEvents in SQL Server 2012

FIX: Nonclustered index corruption may occur when you run a complex UPDATE statement together with a NOLOCK hint against a table in SQL Server 2008, SQL Server 2008 R2 or SQL Server 2012

FIX: The threads are not scheduled evenly in SQL Server 2012 Standard Edition

A memory leak occurs when a SQL Server Native Client OLE DB provider application calls the Prepare method in SQL Server 2012

FIX: “Non-yielding Resource Monitor” when you run a workload that executes concurrent queries in SQL Server 2012

FIX: Function sys.fn_hadr_backup_is_preferred_replica costs almost all the CPU usage in Log Shipping in SQL Server 2012

FIX: Slow performance in SQL Server when you build an index on a spatial data type of a large table in a SQL Server 2012 instance

FIX: Slow performance in SQL Server 2012 when you build an index on a spatial data type of a large table

An access violation occurs when “sys.dm_db_index_physical_stats” is used in an IF EXISTS statement in an SQL query in SQL Server 2012

FIX: Suboptimal execution plan is generated when you run a query in SQL Server 2012

Slow SQL Server performance and a memory leak occurs after you apply Cumulative Update 3 for SQL Server 2012 Service Pack 1

FIX: Slow performance in SQL Server 2012 when you build an index on a spatial data type of a large table

Slow performance or error messages are logged when you have a transactional replication publisher server in SQL Server 2012

FIX: Insufficient system memory error occurs when you try to create an index in a char, varchar, or nvarchar type column in SQL Server 2012

This cumulative update is only for SQL Server 2012 Service Pack 1 (so you must be on Build 11.0.3000 or higher). If you are running SQL Server 2012, I really think you should be on the Service Pack 1 branch by now (or at least be planning to get there soon).
