Virtual (inside the simulation, as you can get with Simulator::Now().GetSeconds()), or wall-clock seconds?
If virtual, then you probably need to define a stop time. e.g. Simulator::Stop(Seconds(100)).
If wall-clock, then your simulation is slower than real-time. Which is pretty common. Wait more. Or reduce simulation time.
