Json value converting error of NetworkHashps #12439

I have a problem to get a NetworkHashps using JSON request after upgrade of 15.01 bitcoin core. so cannot make a mining pool for bitcoin using CoiniumServ..

The issues are Nancy.TinyIoc.TinyIoCResolutionException: Unable to resolve type: CoiniumServ.Pools.INetworkInfo ---> Nancy.TinyIoc.TinyIoCResolutionException: Unable to resolve type: CoiniumServ.Pools.NetworkInfo ---> System.Exception: There was a problem deserializing the response from the coin wallet. ---> Newtonsoft.Json.JsonSerializationException: Error converting value 1.98121075128195E+19 to type 'System.UInt64'. Path 'result.networkhashps', line 1, position 158. ---> System.OverflowException: Arithmetic operation resulted in an overflow.

So I want to know where should I changed to prevent this error.

Dears,

This is a CoiniumServ code for handling Json response.

/src/pool/DaemonBase.cs private DaemonResponse GetRpcResponse(HttpWebRequest httpWebRequest) { string json = GetJsonResponse(httpWebRequest);

    _logger.Verbose("rx: {0}", json.PrettifyJson());

    try
    {
        return JsonConvert.DeserializeObject<DaemonResponse<T>>(json);
    }
    catch (JsonException jsonEx)
    {
        httpWebRequest = null;
        throw new Exception("There was a problem deserializing the response from the coin wallet.", jsonEx);
    }

src/Daemon/DaemonResponse.cs [JsonProperty] private UInt64 NetworkHashps { get; set; }

[JsonIgnore]
public UInt64 NetworkHashPerSec { get; set; }

[OnDeserialized]
internal void OnDeserializedMethod(StreamingContext context)
{
    NetworkHashPerSec = 0;

    if (NetMHashps > 0)
        NetworkHashPerSec = (UInt64)(NetMHashps*1000*1000);
    else if (NetworkGhps > 0)
        NetworkHashPerSec = (UInt64)(NetworkGhps * 1000 * 1000 * 1000);
    else if (NetworkMhps > 0)
        NetworkHashPerSec = (UInt64)(NetworkMhps * 1000 * 1000);
    else if (NetworkHashps > 0)
        NetworkHashPerSec = NetworkHashps;

You can't represent this value as a uint64 anymore, you'll need to use a double or a larger integer type.

This has nothing to do with a change in Bitcoin Core, but with the fact that the network's hashrate is now too large for your software to deal with.

@sipa, thanks your advise. I will made change and update here
