自从我开始将 Outlook 与 GoogleCalendarSync 一起使用以来，我每隔一段时间就会遇到挂起。我使用 ADPlus 创建进程的挂起转储（使用adplus -hang -pn outlook.exe -o c:\dumps）。当我通过 WinDBG 读取转储时，我使用命令!analyze -v -hang，但我无法弄清楚到底出了什么问题。该命令的输出是：

我该如何进一步调查这个转储？我错过了什么？

GoogleCalendarSync 正在运行的线程试图释放一个 COM 对象，其公寓模型是 STA，即该对象存在于单个线程中。这种对象在 COM 之初就非常流行，因为 COM 层保证了对象不会同时被多个线程访问，从而避免了在对象实现中添加同步代码。

您可以获取 GetToSTA 的第一个参数（在本例中为 0x00192888），将内存的内容转储到此地址（dc 0x00192888）。结果，跳过前 2 个 DWORD ：下一个 DWORD 应该是目标进程 ID，下一个是目标线程 ID。这个目标线程很可能已经在另一个操作中被阻塞（参考http://blogs.msdn.com/b/tess/archive/2008/06/12/asp-net-case-study-deadlock-waiting-in -gettosta.aspx，如果你需要一个真实的例子）。
