The sender and the responder is unmodified (node1, node3). I have debugged the hole SMI, ib_mad_recv_done_handler and handle_outgoing_dr_smp functions and did not found the bogus extra response. As debugged is the responder sending one packet, which would be right and the intermediate node isn't receiving an bogus extra packet. So the extra packet didn't pass the SMI that's for sure. I use the libibumad to implement the forwarding mechanism and also use the select function to catch any receive I should handle. Maybe there is something wrong.
