This read-only counter tallies packets dropped by a pipe because the firewall's CorePlus engine ran out of packet buffers under excessive queuing, with the description noting the dropped packet is always the one queued longest globally, so the most overloading connection bears the loss. A rising count here is a more severe congestion signal than clvPipeDelayedPackets, since data is actually being discarded rather than merely delayed. For example, a sustained increase in clvPipeDropedPackets on a pipe would prompt an admin to either raise that pipe's bandwidth allocation or identify and rate-limit the specific connection that's overloading it.
