      We have a single replica set with 3 nodes running 3.0.6 with WiredTiger. The hosts are running 14.04 LTS Ubuntu in AWS. The instance that we use is I2.8xlarge with 240GB RAM.

      Today we had a primary crash with oom-killer. Another primary was elected and within about 5 minutes even that server invoked oom-killer.

      Here is one those server's syslog output : http://pastebin.com/Q7bQP34V
