Mongos stress test was running on undersized machines:
- 4GB memory
- 3 node replica set
At first the system killed one of the replica nodes when it hit Out Of Memory condition (2015-01-29T22:58:49.832+0000)
Later (2015-01-30T01:38:09.637+0000) the second replica node crashed with a segmentation fault (signal 11)
