I at first thought maybe same, but I don't think THP was introduced
until 2.6.38...OP is running 2.6.32-431.11.2.el6.x86_6.  Maybe it's
NUMA related, but would not be idiomatic of NUMA issues as I
understand them (poor memory utilization/high IO utilization).  Would
be a very cheap/easy thing to try though.

Is this server virtualized?
