WPF 内存不足异常

【问题标题】：WPF Out of memory exceptionWPF 内存不足异常
【发布时间】：2017-07-20 07:16:27
【问题描述】：

我有一个 WPF 应用程序，它在生产中运行良好，直到上周。根本没有任何变化，但它开始变慢并因以下错误而崩溃。这是基于 .NET 4.0 构建的，并且已经投入生产多年。对此的任何意见都将受到高度赞赏。尝试了许多从开发环境复制的方法，但根本没有发生。

    Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

Exception Info: System.InvalidOperationException

选中时，用户 PC 中仅安装了 .NET 4.7。只是想知道这是否可能与 .NET Framework 版本相关联？

【问题讨论】：

  • 您有任何相关代码可以帮助我们找到问题吗？事实上，这个问题很模糊。
  • 很遗憾没有。我仍在检查是哪部分代码导致了这种情况。
  • 我在connect.microsoft.com/VisualStudio/feedback/details/3138410 创建了一个连接问题来跟踪这个问题。如果您能够收集内存转储（@codekaizen 的建议我很贴切），请您通过 Connect 链接与我们分享吗？报告中显示的特定堆栈可能不是发生内存不足情况的位置。
  • @Arun - 您是否能够获得故障转储或其他可操作的证据？如果是这样，请将其附加到 Vatsan 创建的 Connect 错误中。我们担心这可能是 .Net 4.7 的问题，但我们无法重现该问题，因此我们需要您的证据。缺少这一点，我们将不得不以 NotRepro 的形式解决该错误。
  • 不幸的是，还没有可操作的证据。要求用户从现在开始尝试较低版本的 .NET。尚未获得反馈。

【解决方案1】：

您可以在生产环境中做的一件事是使用procmon.exe from Sysinternals (Microsoft)。您只需要 exe 即可从磁盘或 USB 驱动器甚至网络共享运行它。

您可以将其设置为在OutOfMemoryException 上转储进程内存：

procdump -ma -e 1 -f OutOfMemoryException -w "<Your Process Name>"

或者，您可以将其配置为在内存超过阈值时触发转储：

procdump -ma -m 1000 -w "<Your Process Name>" -n 20 -s 60

这会将 procdump 设置为为名为 (-w) 的进程转储超过 1000MB (-m) 的所有内存 (-ma)，每次转储之间间隔 60 秒进行 20 次转储 (-n) ( -s)。比较这些可以让您更好地了解一段时间内的内存使用情况。

拥有转储 (.dmp) 文件后，您可以使用各种工具（我喜欢 .Net Memory Profiler 但 PerfView 或 WinDbg with SOS work well, too）来检查转储的堆内存，以确定是否有对象应该不在记忆中。对于 WPF，有典型的罪魁祸首，and property binding (what your callstack is showing) is one of them。

【讨论】：

  • 谢谢！我会试试的！
【解决方案2】：

互联网上有类似的报道，关于相同的callstack 不断重复导致异常，你会得到一个OutOfMemoryException，但你也可以得到一个StackOverflowException 或其他。

这里有类似的问题：error 1 - error 2

不幸的是，调用堆栈不足以了解问题的根源，因此我的建议是在客户端计算机上使用远程调试器来检索有关该问题的更多信息。

【讨论】：

  • 感谢您的建议。现在我也不清楚是哪一部分代码导致了这种情况。我会按照你的建议尝试远程调试器。
  • 这些似乎与@Arun 的问题不同。
  • @Vatsan：确实如此，95% 的调用堆栈是相同的，PropertyChanged -> InvalidateForceInheritPropertyOnChildren -> Coerce ...
  • 它们不一样。 1 是由于 Intellisense 中的可重入集合更改导致的 OutOfRange 异常，2 是 5 年前修复的 Diagram 中的 NullReference 异常。对于 OutOfMemory，调用堆栈不一定相关 - 只是内存用完时发生的情况。故障转储更有用。
