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;
}
....
