C# System.ComponentModel.Win32Exception (0x80004005): 没有足够的存储空间来处理此命令

[英]C# System.ComponentModel.Win32Exception (0x80004005): Not enough storage is available to process this command

长时间(一到两周)运行我的应用程序(.Net 4.5、64 位、WPF)后,我遇到以下应用程序崩溃:

Faulting application name: XY.exe, Version: 2.12.2.2, Time: 0x5bade142

未处理异常的日志记录还显示:

System.ComponentModel.Win32Exception (0x80004005): Not enough storage is available to process this command

我已经在 web.archive.org 上找到了一个包含问题connect.microsoft.com基本描述的链接,我从JordiCorbilla/atom-table-monitor (GitHub)下载了一个运行的 AtomMonitor。 事实上,我发现随着时间的推移,我的应用程序创建了越来越多的 RWM Atom(几天后大约 4000 个)。 这符合异常消息。 所有字符串如下所示:

C1FE = HwndWrapper[XY.exe;;b68ce81a-d29f-414b-b63a-3b6979e33dd3]  --RWM

从异常消息中,我看到一个“弹出OnIsOpenChanged ”正在导致OnIsOpenChanged方法中的RegisterClassEx

但是,在我的应用程序中打开和关闭几个弹出窗口并并行监控 RWM 原子的数量,我看不到任何增加,这就是为什么我找不到问题的确切根源。 过了一段时间,再次查看统计数据时,我可以看到计数增加了。

所以我的问题是:

  1. Popup可以负责提高 RWM 原子的数量吗? 如果是,这是一个错误吗? 为什么它会创建一个新Window并注册这些原子?

  2. 我是否以错误的方式使用Popup 我必须关闭/处置/释放某些东西吗?

  3. Popup是问题吗?

  4. 应用程序创建或不应超过的 RWM 原子的“正常”数量是多少,因为据我所知,它们不能再被删除。

经过一番研究,我发现以下内容: 它与弹出窗口或任何“真实”窗口无关。 除此之外,关闭弹出窗口会释放原子表中的条目。

原因是:我们为图像处理的不同任务创建了 WriteableBitmaps。 总是当新线程用于此任务(创建 WPF 控件)时,会创建一个 Dispatcher,然后创建一个 HwndWrapper。

如果不手动关闭调度程序,则不会释放这些资源。 现在我们使用以下链接中的解决方法:

GitHub:当 WPF 耗尽内部资源时抛出 Win32Exception

SO:为什么使用 JpegBitmapDecoder 的 LongRunning 任务 (TPL) 会耗尽资源?

Microsoft Connect:System.ComponentModel.Win32Exception (0x80004005):没有足够的存储空间来处理此命令

SO:在后台线程中创建可冻结对象时出现资源泄漏
