paraview python script : Delete(renderView1) does not free memory

Question

I am trying to load multiple state files by running a python script with python shell. The script is the following

#### import the simple module from the paraview
from paraview.simple import *

for time in range(0,200):
        renderView1 = GetActiveViewOrCreate('RenderView')

        # destroy renderView1
        Delete(renderView1)
        del renderView1

        filename = 'filepath/filename-%s.pvsm' % time
        servermanager.LoadState(filename)
        renderView=SetActiveView(GetRenderView())
        Render()
        # get layout
        viewLayout = GetLayout()

        # save screenshot
        SaveScreenshot('filepath/filename-%s.png' % time, layout=viewLayout, magnification=3, quality=100)

I was monitoring the memory used by machine, after some time steps the memory used by the machine is whole RAM. Can anybody tell me what I am doing wrong here.

I appreciate your time and support.

Thanks Raj

As suggested by Utkarsh the following script solved my problem. For details see this answer.

--------------------------------------------------------------------------------
from paraview.simple import *

def ResetSession():
    pxm = servermanager.ProxyManager()
    pxm.UnRegisterProxies()
    del pxm
    Disconnect()
    Connect()

for i in range(0, 10):
    ResetSession()
    servermanager.LoadState("/tmp/sample.pvsm")
    renderView=SetActiveView(GetRenderView())
    Render()
