"no endpoint listening" WITH "no connection could be made because the target machine actively refused it"

Question

We are having a rather intermittent issue with our enterprise application where were are getting an "EndPointNotFoundException" that we could not find the issue. However, on some off chance while debugging the solution we came acrossthe error and were able to grab the inner exceptions. I should note that before we got this error there was a communication error right before it (for a task manager) but the data for that was not captured, unfortunately.

System.ServiceModel.EndpointNotFoundException was unhandled by user code
  HResult=-2146233087
  Message=There was no endpoint listening at http://localhost/GetData.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

We think it might be our contract with services being violated for that connection when ever it fails since it "ACTIVELY" ignores the request but other than that we are not sure.
