    Generator Db connect timer and disconnect session can be called
    from concurrent threads and hence generator session can be NULL
    when Db connect init is called from the timer expiry. Fix is to
    add a disconnected flag which is set when disconnect session is
    called and not do Db connect init if generator is disconnected.
    Fixed couple of places in collector where generator disconnect
    session was not being called.
