Hello,

I'm running 10-RELEASE on a HP Proliant DL160 Gen8 and I'm seeing the
following in my kernel logs:
sonewconn: pcb 0xfffff8010e561310: Listen queue overflow: 8 already in
queue awaiting acceptance

I already raised kern.ipc.soacceptqueue to 1024 and  netstat -naA | grep
"fffff8010e561310" returns nothing

Any idea what could it be ..?

I've put some statistics here https://dpaste.de/t8kJ/raw

The machine is running Apache 2.4 (with accf_http/accf_data loaded), PF,
some webapps (ruby on rails, php-fpm, python, ...), ..

Thanks,
Julien
