I have been trying to reduce our swapping:

The cluster is running on Azure VMs (ES is actually running on a secondary hd):

On one of the nodes:

- I have ES\_HEAP\_SIZE set to 14g

- I have the Windows Virtual Memory page file disabled

- I have mlock enabled

I still have these warnings about swapping. Note that I have not rebooted the VM. I don't want the node to be down that long. Is that required?

Any idea how to tune this?
