Can't avoid swapping on Windows cluster

Elastic Stack Elasticsearch
8

No, ElasticHQ does not misrepresent anything. It just reports the numbers it gets from GET _nodes/stats, stats.os.swap.used_in_bytes in this case. Before, I've tested both settings in ealier and 2.4.x as mentioned by @forloop

They never work. On my current ES 2.4.0 node, bootstrap.memory_lock: true is set, and paging file is disabled, yet the used swap is still a very big number

mlockall is active

"process" : {
        "refresh_interval_in_millis" : 1000,
        "id" : 7444,
        "mlockall" : true
      }

still high used swap in _nodes/stats

"swap": {
          "total_in_bytes": 207222677504,
          "free_in_bytes": 17371148288,
          "used_in_bytes": 189851529216
        }

Physical memory is 192GB. Similar high swap is reported on all other Windows ES nodes
