Hello everyone,

I hope you are doing well. I am receiving this error when I am generating a third consumer in the mobility tree walk example.

A common cause for this problem is to enable ASCII tracing after sending any packets.  One way to fix this problem is to call ns3::PacketMetadata::Enable () near the beginning of the program, before any packets are sent.", file=../src/network/model/packet-metadata.cc, line=61

Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

Anyone know what could be the cause?
