max packet count reached
Error message
max packet count reached
What it means
Sentinel error indicating the global packet-count cap (-pn/-max packet limit in Config) has been reached; wrapped in a PacketLimitError with Sentinel=ErrMaxPacketReached so callers can test with errors.Is. Fires when the currentTotal sent across the scan reaches maxPacketCount, causing CanSendPacket to refuse further sends.
Solutions
- Raise or disable the packet limit flag (e.g. -pn 0 / larger -num) if the traffic volume is expected
- Check the limit/current fields on PacketLimitError to confirm the cap that fired
- Split the scan into multiple runs with smaller target sets

Strategy: validation
