TAPI Server Leaks Memory When Multiple Programs Own Calls (310626)



The information in this article applies to:

  • Microsoft Windows 2000 Server SP1
  • Microsoft Windows 2000 Server SP2

This article was previously published under Q310626

SYMPTOMS

Memory leaks slowly in Tapisrv.exe when more than one program is working with the same incoming call. For example, call center program architecture may necessitate that multiple processes own a given call. When this occurs, some tracking data that is associated with call handles may not be freed when the last reference to the call is dropped by using lineDeallocateCall. The amount of memory that is leaked by each call is at least 40 bytes, and is directly proportionate to the total number of call owners, where the number of owners is greater than 2.
