Could you please provide the complete o/p of the following
with 16K ?

1) /proc/meminfo

http://pastebin.com/Eszwp1cS

HugePages_Total:    2019
HugePages_Free:     2019
HugePages_Rsvd:        0
HugePages_Surp:        0
Hugepagesize:      32768 kB

That clearly tells you whats wrong. You have 2019x32M in hugepages.
Could you try releasing them and see if it solves the memory issue ?

$ echo 0 > /sys/kernel/mm/hugepages/hugepages-32768kB/nr_hugepages


btw, whats your root file system(to be more precise, the init) ?

Cheers
