我们将此转储发送给MS,他们将这些结果发回给我们。我试图复制这个,以便我们可以找出为什么Web应用程序在另一台服务器上崩溃。我的评论以@@@开头。非常感谢任何帮助。

0:025> !critlist @@@ *This command is no longer available so I used !locks*
CritSec at 786dd8e0.  Owned by thread 25. 

线程25持有关键部分(或缺少),下面是线程正在等待它。

这个锁的影响@@@ 我可以在Debug Diag Tool中重现这个

70.42%的线程被阻止

- 重建堆栈:@@@我无法找到如何重建堆栈以生成下面的结果。我需要知道哪个DLL导致锁定。在此示例中为secSSo.dll。一旦我发现我可以使用命令lmvm来找到线程的所有者。

- 所以要么线程25已经泄漏了Criticalsection,要么什么都不做,其余的线程只是在等待它。
