Reduces risk of timeouts in case Icinga takes its time to respond. The timeout of 15 seconds introduced earlier has been kept. Chunk sizes were chosen as follows: - 1000: Cheap calculations (object features, check scheduling) - 500: Expected disk writes (comments) - 250: Process check result, Downtimes, Acks
