Your kernel is refusing to do mmap().
We need a bit more info, kernel version, kernel parameters,
Are you on the latest master?

Hi VPP dev guys,
Does Anybody see the failures about vpp on master branch as
following? The failures must be reproduced on my 3 servers/boxes. How can I
fix it ?
vlib_physmem_shared_map_create: pmalloc_map_pages: failed to mmap 1 pages at
0x7fd940000000 fd 25 numa 0 flags 0x42011: Invalid argument
dpdk_buffer_pool_create: failed to allocate mempool on socket 0
Thanks
Zhiyong
