我有一个使用以下方法并行上传 CloudBlockBlob 的应用程序

UploadFromStreamAsync MSDN 文档

CloudBlockBlob.UploadFromStreamAsync Method (Stream, AccessCondition, BlobRequestOptions, OperationContext)

有时我观察到由于下面提到的异常，文件上传出错。

Microsoft.WindowsAzure.Storage.StorageException: The remote server returned an error: (400) Bad Request. ---> System.Net.WebException: The remote server returned an error: (400) Bad Request.
   at Microsoft.WindowsAzure.Storage.Shared.Protocol.HttpResponseParsers.ProcessExpectedStatusCodeNoException[T](HttpStatusCode expectedStatusCode, HttpStatusCode actualStatusCode, T retVal, StorageCommandBase`1 cmd, Exception ex)

   at WKHMR.SSR.Common.Azure.Storage.AzureBlobStorage.<UploadFileAsync>d__32.MoveNext()


StatusMessage:The specified block list is invalid.

ErrorCode:InvalidBlockList

有谁知道这个错误的可能原因是什么？以及如何解决？
