HttpRequestException from SendMessageTemplate

[brunoblank]

Hi, we have started seeing HttpRequestExceptions from the SDK when the send-load increase

Here is the stacktrace:

System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.IO.IOException: The server returned an invalid or unrecognized response.
   at System.Net.Http.HttpConnection.SendAsyncCore(HttpRequestMessage request, CancellationToken cancellationToken)
   --- End of inner exception stack trace ---
   at System.Net.Http.HttpConnection.SendAsyncCore(HttpRequestMessage request, CancellationToken cancellationToken)
   at System.Net.Http.HttpConnectionPool.SendWithRetryAsync(HttpRequestMessage request, Boolean doRequestAuth, CancellationToken cancellationToken)
   at System.Net.Http.RedirectHandler.SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
   at System.Net.Http.HttpClient.FinishSendAsyncBuffered(Task`1 sendTask, HttpRequestMessage request, CancellationTokenSource cts, Boolean disposeCts)
   at Mandrill.MandrillApi.Post[T](String path, RequestBase data)
   at Mandrill.MandrillApi.SendMessageTemplate(SendMessageTemplateRequest request)

I assume there should be a Mandrill-Exception for this case.

Thanks
Bruno
