I am using WCF service in my client-server application and I am facing following error while communication between server and client.
Error Message =>> System.ServiceModel.CommunicationObjectAbortedException: The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it has been Aborted.
Server stack trace:

Application Scenario : Client is getting data from server through WCF service and using nettcp binding. Server is connected with real device and generating 20-30 events every seconds. Generated events are pushed as string message to all connected clients using callback interface of WCF. It's working fine if client have no any process load (just receive event and display). But it gives error when we do some loading process at client side and busy for some time.
Note: I had already set maximum all timeouts in nettcp binding as below, but still problem not solved.
NetTcpBinding tcpBinding = new NetTcpBinding(SecurityMode.None);
tcpBinding.MaxBufferPoolSize = 2147483647;
tcpBinding.MaxReceivedMessageSize = 2147483647;
tcpBinding.MaxBufferSize = 2147483647;
tcpBinding.ReaderQuotas.MaxStringContentLength = 2147483647;
tcpBinding.ReaderQuotas.MaxDepth = 2147483647;
tcpBinding.ReaderQuotas.MaxBytesPerRead = 2147483647;
tcpBinding.ReaderQuotas.MaxNameTableCharCount = 2147483647;
tcpBinding.ReaderQuotas.MaxArrayLength = 2147483647;
tcpBinding.SendTimeout = TimeSpan.MaxValue;
tcpBinding.ReceiveTimeout = TimeSpan.MaxValue;
tcpBinding.ReliableSession.InactivityTimeout = TimeSpan.MaxValue;
Please guide me is there any other settings required related to communication channel or binding ?

As you mentioned in your question, you have set all timeouts to maximum. So as per my opinion, there should be problem in InstanceContextMode you defined. Which mode you defined in your service ? PerSession, PerCall or Single. There might be PerCall you defined and calling service by same object (globally declared object of service) then it's possible to channel come in fault state or connection disconnected.
So If you defined PerSession mode then use single object (Globally declared) from client side to get data from service. If you defined PerCall option then create new object every time.
Hope this help to you. Please feel free to ask any doubt...
