SYMPTOMS

In Microsoft SQL Server 2005, when you call a method of a component object model (COM) object by using the sp_OAMethod stored procedure, a memory leak occurs. This problem occurs if the method returns the result in the output parameter of the method.

Back to the top

CAUSE

This problem occurs because SQL Server 2005 does not release the memory that is allocated to the variable that holds the output parameter value.

The fix for this problem is in the Odsole70.dll file. The first fixed version of the binary is 2005.90.2232.0.

Microsoft SQL Server 2005 Service Pack 2 (SP2) does not include this fixed binary. If you experience this problem in SQL Server 2005 SP2, you must install a cumulative update to fix this problem.


The first cumulative update that includes this fix is Cumulative update package 2 for SQL Server 2005 SP2. The build for this update is 09.00.3175. Therefore, you can install the latest cumulative update for SQL Server 2005 or any cumulative update that was released after June 2007 to resolve this issue.
