What is a heap?
As per Microsoft: "This event is logged when Windows experiences desktop heap exhaustion". See ME907300 for details.
ME810807 has information on this event.
As per Microsoft: "Windows NT uses a special memory heap for all Windows-based programs running on the desktop. The desktop heap is used for all objects (windows, menus, pens, icons, etc.). When a large number of Windows-based programs are running, this heap may run out of memory. When there is not enough memory to satisfy an allocation request, the system normally returns an error and notifies the user that they are running low on memory. Some programs do not handle the failure gracefully, and in some cases there may not be enough memory to create the error message dialog box. As a result, the requested operation fails without any indication".
You can increase the desktop heap size by editing the registry. See ME126962 for information on this issue.
