我试图找出我们在服务器应用程序中遇到System.OutOfMemoryException的原因。这台机器有256Gb内存和48个内核，当它使用大约50Gb - 70Gb时会出现例外情况，因此会有足够的空间。
我有一个转储，但不幸的是只有在堆栈被解除之后。使用WinDbg和这个命令：
.foreach(tempVariable {!dumpheap -type System.OutOfMemoryException -short}){!pe -nested tempVariable;.echo *************}
我可以看到这种类型的堆上存在很多异常：

因此几乎所有的OutOfMemoryException都在GetResourceFromDefault或Monitor.Enter（）中。我想第一个处理程序试图分配内存来显示异常的语言环境版本？但是Monitor.Enter（）呢？
UNKNOWN模块当然是我们的应用程序..
任何人都有任何线索可以找出导致异常的确切原因？

Edit2更多信息： 我们一直在运行perfmon，我们可以看到的一件事是，在崩溃之前，正在使用的＆＃34; Sink块的数量＆＃34;发疯了它从稳定的200-300,000到600多万......有时它可以从中恢复，但有时它不能然后崩溃。
任何可能导致此问题的线索？
