    Description

      This is probably due to a leak. Mongod runs out of memory and get kicked out from the OS. Memory (as reported by top(1)) looks growing linearly with time.
      Scenario:
      https://github.com/dcci/mongo-stress/blob/master/createdb.sh
      It takes about 2 hours in my machine to reproduce.
      You'll need the mongo C driver and libbsd (the code relies on arc4random()).
