log file fills up 20g hard disk very quickly, and cpu full load

Just set log level=none
@cbeuw commented on GitHub (Jun 7, 2020):
Sorry for the excessive space use caused. It now doesn't try to accept in a tight loop but instead retries with gradually increasing pause. But have you been DDOSed when this accept error started?
@qwerttvv commented on GitHub (Jun 8, 2020):
no one attacked...only i know the ip address.
and usage statistics is here
by the way, i set iptables rule like this
-A FORWARD -p tcp -m tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu@qwerttvv commented on GitHub (Jun 12, 2020):
