[one-users] A question about the utilization of VMs

Could that the memory no freed be in the cached/buffers?

No there is no specific access to that. ONE prepares the deployment
file by setting the max memory <memory> and does not set
<currentMemory>

Are you sure that the memory is no cached (i.e. will be freed when
request by the kernel?)
