Watching my pfsense log 2.3.4 nanobsd running on apu2c4 I see this strange log:
sonewconn: pcb 0xfffff8000689b960: Listen queue overflow: 193 already in queue awaiting acceptance (468 occurrences)
what's happened ?
thanks in advance
You have some daemon on the firewall which is extremely busy, connections are coming in too fast for it to handle with the current queue size.
What services and packages do you have enabled?
