Hi, I'm new to NS. I have been trying to set up a simulation with 10 mobile nodes (DSDV), 20 exponential on/off flows between sources/sinks (defined in the script), all using UDP as transport protocol. However, if I set the rate parameter for the exponential traffic sources to a number greater than 1 (say 10kb), I get a "segmentation fault." What am I doing wrong??? Thank you, Roberto Barnes
