Description Tommaso Pecorella 2013-12-24 10:52:37 UTC

FlowMonitor relies on the presence of a "Simulator::Stop (some_time_in_the_future);"

If the user forgets this, the simulation will run forever.

The root problem is in this function:
void FlowMonitor::PeriodicCheckForLostPackets ()

This is a truly periodic function, and if nobody is stopping it... it will go on forever. And the simulation with it.
