문제

윈드 워드 in windbg누출을 처리하십시오. 콜스터를 표시하지 않는 핸들 (아마 누출 된 것들 아마도 누출 된 것)을 얻습니다.

이 이유가 될 수있는 이유와 어떤 옵션을 더 이상 디버깅해야합니까?

갱신 : 핸들 누수가 그래픽 드라이버 또는 그래픽 카드에 따라 다릅니다.특정 그래픽 카드 / 드라이버가있는 일부 Windows XP 시스템에서만 누출 된 WPF 만 누출되면 누출이 발생합니다.

해결책

Calls are performed in kernel mode by ZwOpenProcess routine (http://msdn.microsoft.com/en-us/library/windows/hardware/ff567022(v=vs.85).aspx) and not followed by a ZwClose call. Then the handle leaks. You don't see the callstacks because they are only available when calls are performed from user mode (OpenProcess / CloseHandle).

On an XP SP3, it seems difficult to find the culprit. The solution would be to use the 'Object reference tracing' functionality built in the OS, but this path is paved with issues (see http://www.osronline.com/showthread.cfm?link=198302 for further references). Since you found out this issue arises only when a particular video card is present, you can try to contact the vendor or check for a newer version of the driver.
