Question

我们正在使用3.4.3的ImageResizer和精英插件。似乎我们遇到的任何麻烦都与Faces插件有关。图像不会显示，并且在查看网络响应时，堆栈跟踪显示“代理不能从本机代码封送到除其主域之外的域”。完全跟踪在这里

我找到this page并确保我们没有使用重叠回收。我尝试升级到4.1.7，但尝试将所有opencv版本/位数排成一行是一个噩梦。该应用程序会经常崩溃，并根据它的人质保留其余的网站，所以我们回滚到3.4.3，至少有效，然后没有。当我们重新启动IR应用程序池时，我们的常规问题会暂时消失。

我们的网络应用程序托管在由BigIP进行负载平衡的两个VMS上。每个VM都有两个Web应用程序，它们共享一个托管在同一服务器上的图像缩放器，并使用URL API进行调整大小请求，面部检测+裁剪等。

我能够获得的另一个信息来自DebugDiag。我抓住了应用程序的崩溃，并显示以下消息：


In w3wp__ImageResizer__PID__5284__Date__06_14_2017__Time_08_23_10AM__122__First chance exception 0XE0434352.dmp the assembly instruction at KERNELBASE!RaiseException in C:\Windows\System32\KERNELBASE.dll from Microsoft Corporation has caused a CLR Exception on thread 28 with the following error information:
    Type:   ImageResizer.Plugins.Faces.AlternateResponseException 
    Message:   Resizing was canceled as JSON data was requested instead 
This exception originated from ImageResizer.Plugins.Faces.FacesPlugin.Render(ImageResizer.Resizing.ImageState).

偶尔500s使用Faces插件 - 代表无法编组
