This object sets the first, lowest, accounting buffer fill-level percentage that, once crossed, generates a warning notification but takes no other action. An admin uses this as an early, low-severity heads-up that the accounting collection pipeline is falling behind, giving time to investigate before the more disruptive chasAccountThreshold2, which forces a collector failover, is reached. Setting this object to 40 means a warning trap fires as soon as the accounting buffer reaches 40% full, well before any connection-switching action occurs at the higher thresholds.
