What is a "node" ?
If this is some kind of virtual machine rather than physical, you should include that info when asking memory management questions.
Some virtual machines have very confusing memory management behaviors, very different from a physical machine. So if you try to apply methods appropriate to a physical machine, you are just interfering with the designed behavior of the virtual machine.

hown can i free up the swap memory?

Why do you want to?
If a physical machine running correct applications and services has used most of its swap space, that probably means you didn't configure enough swap space. You should be adding more swap space, rather than trying to free what has been used.
If some services that you don't need are running and causing use of swap space, you should be trying to identify those and stop them, rather than trying to do something system wide about a service specific problem.
Similarly, if some application or service has a memory leak, you should identify and address the specific problem.
