bretagne-peiqi commented 6 years ago

maybe it related with code: src/ipv4_frag.c:405.
I am not sure for the moment

Pls try to use bigger hugepage setting like this:

echo 10240 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

echo 10240 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages
