Azure 崩溃转储：远程服务器返回错误：（412）未满足指定的附加位置条件

我们在Azure Web应用程序的IIS上运行的应用程序偶尔会崩溃。我已经使用监视了该过程，并从Azure存储库中获取了抛出的

WebException

我们正在Azure web应用程序上使用

WindowsAzure.Storage

8.1.4库托管一个.NET 4.7 64位web应用程序（带Kestrel）

从调用堆栈判断，这似乎不是来自我们的代码本身（如果我错了，请纠正我）。我们确实使用内置功能将web和应用程序日志保存到blob存储中-可能就是这样吗

例外信息 在xyz.dmp中，KERNELBASE上的汇编指令！引起异常 来自Microsoft Corporation的D:\Windows\System32\KERNELBASE.dll已 导致线程202上出现CLR异常，错误如下 资料:

Type:   System.Net.WebException 
Message:   The remote server returned an error: (412) The append position condition specified was not met.. 

此例外源于 系统!！System.Net.HttpWebRequest.EndGetResponse（System.IAsyncResult）
