FIX: Winsock Over Appletalk (DDP) Leaks Memory

ID: Q131159

The information in this article applies to:

• Microsoft Win32 Software Development Kit (SDK) for Windows NT version 3.5

SYMPTOMS

A memory leak occurs when you open a socket with address family AF_APPLETALK, type SOCK_DGRAM, and protocol ATPROTO_BASE + x (where x is a user-defined number except the ones that are reserved - please refer to the SDK header file ATALKWSH.H); then once a server is located to send data to, you send data to it.

Observing with PerfMon, you can see that non-paged memory use keeps on increasing. It does not decrease even after the application is stopped. If the application is allowed to continue for a long time, the results are unpredictable and it is neccessary to restart the computer.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Windows NT version 3.51.
