I want to take screentshot of renderWindow.  
So I am using “vtkRenderLargeImage” for that

I have used offScringRenderig.

```auto
renderWindow.SetOffScreenRendering(1)

```

```auto
w2Image = vtk.vtkRenderLargeImage()
w2Image.SetInput(inRen)
w2Image.Update()

```

It working fine on local system and on server.

But when I used it “celery task manager” it restart celery task without showing any errors.  
Just below messages are showing

```auto

--- ***** ----- 
-------------- [queues]
                .> celery exchange=celery(direct) key=celery

```

Anyone have any idea about this?  
Please help me to solve this issue
