The issue can be reproduced with example program l2fwd by modifying it to sleep 1 second before launching thread.
code like this: .... check_all_ports_link_status(nb_ports, l2fwd_enabled_port_mask); sleep(1); /* launch per-lcore init on every lcore */ rte_eal_mp_remote_launch(l2fwd_launch_one_lcore, NULL, CALL_MASTER); RTE_LCORE_FOREACH_SLAVE(lcore_id) { if (rte_eal_wait_lcore(lcore_id) < 0) return -1; } ....
