If the no of objects are to to be inspected or inspected objects are
completed within time duration then it shuts off by itself.

In my case when I wanted to run for duration=10.
Then issued the cmd query proc I can see that as all objects get inspected
within the time it gets shuts off because
it has nothing else to inspect .PL do that again and see that how much time
it takes to inspect and expire.
This is what I saw in my case .It need not run all the duration in idle for
left out time.
