我有一个在 IIS 8.5 上运行的应用程序，它突然挂起。
我已经在确切的时刻转储了内存并试图分析问题，我发现了以下内容：
<块引用>w3wp.exe_210419_122423.dmp 中的以下线程正在等待进入线程 128 拥有的 .NET 锁
如果我理解了这条消息，这意味着一个线程正在锁定其他线程（76 个线程），但我没有弄清楚到底发生了什么。
查看线程 128，我有以下内容：
Thread 128 - System ID 27172
Entry point clr!Thread::intermediateThreadProc
Create time 19/04/2021 12:06:21
Time spent in user mode 0 Days 00:00:00.734
Time spent in kernel mode 0 Days 00:00:00.171
This thread is not fully resolved and may or may not be a problem. Further analysis of these threads may be required.
