You probably just need to ensure that you've got more than one period
so there's always one ready, increase min_periods or possibly make the
individual periods bigger.  It's normally going to be very hard to get
everything scheduled reliably if there's no margin for error, ensuring
there's some grace in case things run over will tend to be more robust.
