Mono HTTPS异常-身份验证或解密失败

当尝试通过HTTPS发布一些数据时，我间歇性地得到此异常。运行在mono 2.10.1(现在更改为2.10.9)。我不知道为什么会发生这种情况，它似乎与请求大小(约2.5MB)无关，因为其他类似大小的请求正在工作。

// these arguments are not null, as I can see them in a log.
var response1 = web1.UploadData(address, "POST", buffer);

堆栈跟踪mono 2.10.1:

System.Net.WebException: An error occurred performing a WebClient request. ---> System.IO.IOException: IO exception during Write. ---> System.NullReferenceException: Object reference not set to an instance of an object
  at Mono.Security.Protocol.Tls.SslStreamBase.InternalBeginWrite (Mono.Security.Protocol.Tls.InternalAsyncResult asyncResult) [0x00000] in <filename unknown>:0

与mono 2.10.9我得到一个不同的错误:

Mono HTTPS异常-身份验证或解密失败

这似乎是网络层应该处理的间歇性网络问题。在随后的尝试中，这个问题就消失了。

证书无效。我找到的唯一方法是捕获异常并重试请求，创建一个新的WebClient对象(因为一些header被清除)。

我基本上把代码放在一个循环中，它试图多次上传数据。

int maxAttempts = 5;
for (int attempt = 1; attempt <= maxAttempts; attempt++) {
    try {
        if (attempt > 1) {
             // Wait a few seconds
             Thread.Sleep(new TimeSpan(0, 0, 10));
             Logger.Output(string.Format("Retrying request, try: {0}", attempt));
        }
        using (var webClient = new WebClient()) {
            webClient.Headers.Add("Content-Type", string.Format("multipart/form-data; boundary={0}", boundary));
            Logger.Output(webClient.Headers.ToString());
            var response1 = webClient.UploadData(address, "POST", buffer);
        }
        Logger.Output("Table {0} added successfully", table);
        break;
    } catch (WebException e) {
        // More logging here
        if (attempt == maxAttempts) {
            throw; // Re-throw it, clearly something is wrong if it fails x times.
        }
    }
}

The authentication or decryption has failed.可能是mono的bug，使用curl应该可以工作。
