Hi Henry, Could you provide the output of vmstat 5 5? vSwap has absolutely nothing to do with the swap on the host. Think of vSwap as slow burst ram. If all your containers decide to hit vSwap at the same time though, the host may start using REAL swap. Try setting swappiness to 1 (I don't recommend 0 as there were bugs in the past related to that).
