[Paraview] pvserver does not terminate after gui disconnects

[pratik]

Hi Utkarsh,

Please excuse me on this, but the cluster that I was working on will not 
be available for me for the next
week or so. As soon as it is back up, i will test this and send it to 
you (most likely by saturday/sunday)

Thanks,
pratik
