A first future time occurs sooner than a second future time. The first future time indicates when the first and second future times are to be evaluated. The second future time provides a boundary between schedules occurring sooner and schedules occurring later. A schedule is generated and added to a database stored in a non-volatile storage. The schedule is for executing, in relation to an incident, an incident-handling action corresponding to a condition matching the incident. The schedule has an execution time at which to execute the incident-handling action in relation to the incident. Where the execution time is sooner than the second future time, the schedule is added to a queue stored in a volatile memory. Upon a current time equaling the execution time, the schedule is removed from the queue and correspondingly executing the incident-handling action in relation to the incident.
