httpd print “std::system_error (error system:103, Software caused connection abort),” when seawreck run with multiple cores and connections

[tedqian]

when run the demo httpd and seawreck application：

httpd application run with the parameters：./httpd --network-stack native --dpdk-pmd --host-ipv4-addr=1.1.1.17 --gw-ipv4-addr=1.1.1.17 --netmask-ipv4-addr=255.255.255.0 -m 64G -c 20

seawreck application run with the parameters：./seawreck --server=1.1.1.17:10000 --smp=40 --conn=40 --reqs=1000000000 --duration=1000 --network-stack native --dpdk-pmd --host-ipv4-addr=1.1.1.18 --gw-ipv4-addr=1.1.1.17 --netmask-ipv4-addr=255.255.255.0 -m 64G

the httpd application print：

if change the --smp=1 --conn=1，it works fine
./seawreck --server=1.1.1.17:10000 --smp=1 --conn=1 --reqs=1000000000 --duration=1000 --network-stack native --dpdk-pmd --host-ipv4-addr=1.1.1.18 --gw-ipv4-addr=1.1.1.17 --netmask-ipv4-addr=255.255.255.0 -m 64G

something wrong with the parameters?
