Wolfram SystemModeler stops after half an hour doing a real time simulation

I am trying to simulate a dynamical system in the simulation center. I set the stop time to be equivalent for 3 days and checked the “Synchronize with real time” option because I want the simulation to be in real time. My problem is that the simulation stops/halts/freezes after about 1700 sec (half an hour). I am not sure if this is a potential bug in system modeler. I want to perform long duration real time simulations and I am not able to do that at WSM.

Thanks

Hi Mostafa,
Please contact Technical Support at support@wolfram.com with your system information and an example model showing this behavior.
