AWS S3下载文件挂起

Question

我正在使用AWS S3存储文本文件，然后使用EC2中的Windows服务下载它们。大约50％的时间我启动服务，从S3下载文件时服务挂起。这是我正在使用的代码：

            GetObjectRequest request = new GetObjectRequest();
            request.BucketName = BucketName;
            request.Key = FilePathAndName;
            using (GetObjectResponse response = objClient.GetObject(request))
            {
                string title = response.Metadata["x-amz-meta-title"];                   

                using (Stream responseStream = response.ResponseStream)
                {
                    using (StreamReader reader =
                        new StreamReader(responseStream))
                    {
                        responseBody = reader.ReadToEnd();
                    }                       
                }
            }

我也尝试过这段代码，而ReadAllResponseStream（）是一种手动读取流的方法，而不是使用reader.ReadToEnd（）：

            GetObjectRequest request = new GetObjectRequest();
            request.BucketName = BucketName;
            request.Key = FilePathAndName;
            using (GetObjectResponse response = objClient.GetObject(request))
            {
                //string title = response.Metadata["x-amz-meta-title"];
                //Console.WriteLine("The object's title is {0}", title);

                using (Stream responseStream = response.ResponseStream)
                {
                    byte[] s3Data = ReadAllResponseStream(responseStream);
                    responseBody = Encoding.UTF8.GetString(s3Data, 0, s3Data.Length);                      
                }
            }

如果我正在使用来自当地场所（EC2之外）的每个代码变体，它似乎工作正常。
