Log entries from around the time of the crash (both from openvpn and OS messages from /var/log/messages) would be helpful. Is there a core dump anywhere? If not, you might be able to get one in /var/crash by setting sysctl kern.nosuidcoredump=2, but it would be helpful to run a build of openvpn from ports done with 'make clean=all; make DEBUG="-O0 -g" repackage && sudo make reinstall' as this will increase the amount of information available if there is a coredump. (If you can get one, use gdb to obtain a backtrace and send that, rather than sending the file itself). > dmesg: > OpenBSD 5.7-beta (GENERIC.MP) #828: Thu Jan 29 14:28:19 MST 2015 > dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP (real/avail mem lines snipped to protect the innocent ;)
