A few answers right away: - Exact freebsd versions affected (uname -a) FreeBSD fbsd-tc.ov.greenie.net 12.1-RELEASE-p2 FreeBSD 12.1-RELEASE-p2 GENE= RIC=20 amd64 - Minimum network configuration necessary to reproduce (/etc/rc.conf, openv= pn or pure tun/tap config (ideally)) Sharing the actual OpenVPN config is complicated (the config is very simple, but it's part of our CI tests, so without "the other end" it won't do much) - truss or similar trace output under reproduction (as an attachment) - /var/run/dmesg.boot output (as an attachment) - confirmation whether openvpn/openvpn-devel from ports/packages also exhib= its this issue. Right now, my system is stubbornly refusing to show the effect at all - but= if it does so, the effect is the same for openvpn (2.4.x) or openvpn-devel (wh= ich is our git master state as of two days ago, with no FreeBSD specific patche= s). While it nicely did this for "80%" of the cases beforehand... I think the easiest way is to write a test program, which I'll do tonight a= nd attach it. --=20 You are receiving this mail because: You are on the CC list for the bug.=
