当我尝试将大文件上传到Azure blob存储时，似乎发生了上述错误。
这是我在声明CloudBlobClient时所拥有的。
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
blobClient.ParallelOperationThreadCount = 1;
blobClient.SingleBlobUploadThresholdInBytes = 67108864;
CloudBlobContainer container = blobClient.GetContainerReference("container");
await container.CreateIfNotExistsAsync();
CloudBlockBlob blob = container.GetBlockBlobReference(blobName);
await blob.UploadFromByteArrayAsync(fileByte, 0, fileByte.Count());
但是，为什么当我已经将ParallelOperationThreadCount设置为1并且发生此异常时呢？
编辑：在下面添加了堆栈跟踪。
