Methods, apparatuses, and computer program products for administering incident pools for incident analysis in a distributed processing system are provided. Embodiments include an incident analyzer receiving a plurality of incidents from an incident queue. The incident analyzer also assigns each received incident to an incident pool having a predetermined initial period of time. The predetermined initial period of time is the time within which the incident pool is open to the assignment of incidents. The incident analyzer calculates an arrival rate that incidents are assigned to the incident pool. The incident analyzer also extends based on the arrival rate, for each incident assigned to the incident pool, the predetermined initial period of time by a particular period of time.
