https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194577 --- Comment #9 from Hans Petter Selasky <hselasky@FreeBSD.org> --- Hi, Here is how to reproduce: FreeBSD-9-stable: 1) install openvpn from ports 2) generate an openvpn key 3) start two instances of openvpn like this (no need for a client!) /usr/local/sbin/openvpn --keepalive 120 240 --float --lport 543 --dev tun3 \ --ifconfig 10.1.2.6 10.1.2.7 \ --secret xxxx.key --daemon testlink /usr/local/sbin/openvpn --proto tcp_server --keepalive 120 240 --float --lport 544 --dev tun4 \ --ifconfig 10.1.2.8 10.1.2.9 \ --secret xxxx.key --daemon testlink2 4) watch vmstat -z | grep -E "LIMIT|mbuf:" After some minutes, the number of mbufs in use starts growing simply. Maybe that's simpler for you to reproduce? --HPS -- You are receiving this mail because: You are the assignee for the bug.
