hi experts,
Can a powered on VM have 0 Kb swap file ( <vmname>.swp )
This VM was deployed via vapp
Later on after some time when i put load on VM .I see a new swap file being created too
the datastore has a new swap file too ( <vmname+somecharacters>.swp)
so my vm has two swap files now 
first one is zero ofcourse.
Why is this happening ??
why is the second swap file being created?
When is a swap file created?What is the purpose / use of it?
