This article was previously published under Q314638 SYMPTOMS
On a Web server that is using Microsoft Data Access Components (MDAC) 2.5 or 2.6, a memory leak may occur when using ODBC to connect to a data source. You can confirm this by using Performance Monitor to track the private bytes allocated by either the Internet Information Server (IIS) process or the DLLHost process under which a particular IIS application is loaded.
CAUSE
ADO internally allocates empty strings for the EXCEPINFO structure in all cases although this structure is only needed in the case of a failed HRESULT.
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
This bug was corrected in Microsoft Data Access Components (MDAC) 2.7.
