Description
My OS is ubuntu server 14.04.2, and my mongodb version is 3.0.
I make a stress test with the new storage engine wiredTiger. But I find the memory usage never reduce. Finally, killed by kernel because of "out of memory"
localhost kernel: [12422.302136] Out of memory: Kill process 5893 (mongod) score 405 or sacrifice child.
