After changing the memory size of the virtual machine containing the vCenter Server Appliance from the default 8GB to a lower size, swapping may occur in the operating system of VCSA. This occurs because the embedded components, including the vSphere Web Client, Inventory Service, and Profile Driven Storage service, do not automatically reconfigure their JVM heap settings proportional to the total memory available to the operating system after the memory size is reduced. Therefore, these components may over-consume memory and cause guest and host level swapping.
