Hello, all
On one of our ESXi hosts, esxtop is showing a constantly high %SWPWT even when all the VMs are off. It is around 20-40% most of the time but often rises to 90%. It all comes from the gsSwapRefill subprocess (ID 65622) of the system process (GID 1). I believe it an abnormal situation. How can I find out what is causing this constant swapping?
