FIX: The SQL Server service consumes lots of memory when you run a query that uses the sys.dm_exec_sql_text dynamic management function in the APPLY operator in SQL Server 2005

In Microsoft SQL Server 2005, you have a query that uses the APPLY operator. You use the sys.dm_exec_sql_text dynamic management function in the APPLY operator. When you run the query, the SQL Server service consumes lots of memory. However, this behavior may cause the server to stop responding.

Additionally, if you run the DBCC MEMORYSTATUS statement, you find that a large amount of memory is consumed by multipage allocations.

If you run the following statement to check the MEMOBJ_XSTMT objects that are currently allocated by SQL Server, the statement returns a very large value:

You have a query that uses the sys.dm_exec_sql_text dynamic management function in the APPLY operator. When you run this query, the SQL Server database engine loads the text for every batch in the execution plan cache into memory. Then, the SQL Server database engine holds the memory until the query finishes. However, this behavior consumes lots of memory.

The fix for this issue was first released in Cumulative Update 4 for SQL Server 2005 Service Pack 3.
