Subscriber stops after a few messages

[florianspy]

Hello everyone, I am experiencing problems with subscribers. I am using the following source code for a subscriber:

using System;
 using UnityEngine;
    namespace RosSharp.RosBridgeClient
  {
      public class StringSubscriber : UnitySubscriber<MessageTypes.Std.String>
      {
          public String messageData;

          protected override void Start()
          {
              base.Start();
          }

          protected override void ReceiveMessage(MessageTypes.Std.String message)
          {
              messageData = message.data;
              //Debug.Log(messageData);
          }

      }
  }

However after about 80 message no new data is received. Even though data is still published. I also tried the following code with the same issue.

using System;
using RosSharp.RosBridgeClient;
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using RosSharp.RosBridgeClient.Protocols;
// commands on ROS system:
// roslaunch rosbridge_server rosbridge_websocket.launch
// rostopic echo /talker
// rostopic pub /listener std_msgs/String "World!"

public class HelloWorld: MonoBehaviour

{
int count;

public Protocol protocol;
void Start()
{ RosSocket.SerializerEnum serializer = RosSocket.SerializerEnum.Microsoft;

RosSocket rosSocket = new RosSocket(ProtocolInitializer.GetProtocol(protocol, "ws://172.16.24.128:9090"),serializer);
    // Subscription:
    rosSocket.Subscribe<RosSharp.RosBridgeClient.MessageTypes.Geometry.PoseStamped >("/listener2",subscriptionHandler);
}
private static void subscriptionHandler(RosSharp.RosBridgeClient.MessageTypes.Geometry.PoseStamped message)
{

    Debug.Log("Hello message"+message);
}
   void Update()
    {
    //Debug.Log("subscriber");
count=count+1;
    }
} 

Thank you for your help.

After creating the problem again from scratch using the rossharp as base of the project https://github.com/siemens/ros-sharp/tree/master/Unity3D. The problem is solved.
