proc/pid/maps output

Spawned a VM with RAM of 188GB and configured Huge page size as 1GB and num=
ber
of huge pages as 100. When tried to allocate mempool using rte_mempool_crea=
te
from testpmd process, after allocating 64 huge pages this call returns below
error message,

"EAL: eal_memalloc_alloc_seg_bulk(): couldn't find suitable memseg_lis=
t"

Though there were 35 huge pages available, mempool creation was failed.

The below call would create 1 huge page,
rte_mempool_create("test6", 1048576, 4096, 512, 0, 0, 0, 0, 0,
(int)rte_socket_id(), 0)

after creating 64 huge pages, this call started to fail. This fails even af=
ter
tweak  the number of pool, element size etc.,

Appreciate if any help on this.
