Dear All,


>>>> I have a system with two numa sockets. Each numa socket has 8GB of RAM.
>>>> I reserve a total of 6 hugepages (1G).


Unless the system was specially crafted, it is very likely that 4GB 
belongs to each NUMA node, thus it is not possible for the kernel to put 
all 6 hugepages into the memory of the same NUMA node.

Perhaps adding another 8GB RAM and reserving 12 hugepages could help.
