我們的Windows應用程序經常掛在內存中，我試圖用windbg跟蹤 解決問題。我對windbg很陌生，可以使用一些建議（儘管我已經開始閱讀高級Windows調試，但我仍然可以使用 ）。診斷未能停止的應用程序
該應用程序是用VB編寫的C++和COM對象的混合。偶爾當您退出時，應用程序似乎會消失，但任務管理器顯示它在內存中掛起大約 ，顯然處於空閒狀態。 ！

爲了我的未經訓練的眼睛，它看起來像它被保持活由被阻止通過一個單線程公寓 敲定隊列。這個 看起來是否合理？

我將在這裏欣賞一點點修正路線。如果我對 封鎖終結者的猜測看起來合理，請告訴我。我也是 很高興得到一些建議，弄清楚什麼是封鎖。

您確定所有創建的對象已正確釋放？最簡單的方法是使用一些不同的auto ptr類。如果你沒有這樣做，你應該。 – eran 2009-06-10 19:46:37
我認爲這個掛起是一個泄露的COM對象的結果。似乎認識到應該有一些方法來找到泄漏的物體與windbg。有什麼建議？另外，我是一個聰明的指針的大信徒，只要我可以避免裸指針。 – criddell 2009-06-11 14:12:28
