> {color:#000000}We have observed a periodic task (in this case, the schema
> reporting task) running twice within the same reporting interval. {color}
> {color:#000000}The unexpected behavior is because the schedule call as part
> of the rescheduling can race with the schedule call at the end of a periodic
> task run. As a consequence, the termination condition of a schedule is
> incorrectly removed, causing multiple schedules of the same task being
> executed.{color}
> {color:#000000}This patch fixes the bug by ensuring a single thread schedules
> the next run{color}
