我的多线程应用程序在C＃2.0中使用线程池挂起每隔几个星期左右的刺。
我做了一个syncblk

我已经删除了数百个像这样的行：
3073 05b4e144 1 1 17c45c30 1884 518 023dfc2c MyProg.MyChildClass
线保持979个监视器被锁定一个ArrayList，但谁正在等待所有其他线程试图获取不同的对象上readerlock。
我知道这锁都读线程试图获取，但我不知道是谁在持有该锁。 如何找到了这一点？
与MonitorHeld = 1的所有主题clrstack和DSO的类似输出。 这里是DSO和clrstack输出线保持979个锁（ID = 45），并等待读取器线程（ID = 290）。 同样的，当我做〜* E！clrstack所有线程与Monitor.Enter具有相同的堆栈在以下2个线程的clrstack
