host id out of bound id {0} max id should be greater 0 and less than {0}

Hi everybody. I recently started getting this error message when I run my project.

host id out of bound id {0} max id should be greater 0 and less than {0}

The code that generated this error worked fine on version 5.3.5f1 but once I upgraded to 5.6.0f3 this error has appeared. I have also tried 5.6.1.f1 but the error persists.

This error happens in a program that uses the lower level API as a server. I get this error when running the program alone, with no clients trying to connect.

This is the snippet of code where the error actually happens.

bool CheckSocketForData(SocketConnection currSocket)
{
Assert.IsNotNull(currSocket);

int maxMessageLen = 1024; // JLTODO

int recConnectionId;
int recChannelId;
byte[] recBuffer = new byte[maxMessageLen];
int dataSize;
byte error;
string message;

NetworkEventType recNetworkEvent = NetworkTransport.ReceiveFromHost(currSocket.socketId, out recConnectionId, out recChannelId, recBuffer, maxMessageLen, out dataSize, out error);

And the socket is created by the code CreateHostSocket

public static SocketConnection CreateHostSocket(string name, int port)
{
HostTopology topology;
var socket = CreateSocketCommon(name, out topology);

socket.socketId = NetworkTransport.AddHost(topology, port);
return socket;
}

static SocketConnection CreateSocketCommon(string name, out HostTopology topology)
{
var socket = new SocketConnection(name);

ConnectionConfig config = new ConnectionConfig();
socket.reiliableChannelId = config.AddChannel(QosType.Reliable);
socket.unreliableChannelId = config.AddChannel(QosType.Unreliable);

topology = new HostTopology(config, 10);
return socket;
}


Any ideas how to proceed?

Thank You

It looks like this is an example of the bug reported here:
