    Description

      We are running several aws ec2 servers with ubuntu 16.04 and mongodb that have all 2GB of ram, but the database does not use more than around 1GB even though the database itself is growing and growing in size.
      also it seems that some process makes the kswapd0 process going nuts trying to swap.

      Is there any hidden setting that limits mongodb in the amount of ram it is allowed to use?
