mongod進程退出， 退出時數據庫中記錄大概1.2億，數據庫小大600G
錯誤信息如下：

mongodb官網上有如下說明，可供參考：
Linux, NUMA and MongoDB tend not to work well together. If you are running MongoDB on numa hardware, we recommend turning it off (running with an interleave memory policy). Problems will manifest in strange ways, such as massive slow downs for periods of time or high system cpu time.
numactl
To turn off NUMA, start mongod with
numactl --interleave=all ${MONGODB_HOME}/bin/mongod --config conf/mongodb.confproc settings
echo 0 > /proc/sys/vm/zone_reclaim_mode
You can change zone_reclaim_mode without restarting mongod. For more information on this setting seehttp://www.kernel.org/doc/Documentation/sysctl/vm.txt.
