This problem is specific to the use of the 32-bit DB-Library API, and the problem only occurs when using the TCP/IP or IPX/SPX network libraries.
For an application that uses a single DB-Library connection, the memory leak will hardly be noticeable. But for applications that either connect/disconnect for each query ("make/break connections") or use multiple connections, the problem can be more severe, causing all of the memory on the computer to be consumed.
