Would you mind installing the openvpn-debug package and then run openvpn via gdb? Then you should be able to get a backtrace of the crash. It might be you need to install gdb as well. Quick crash course to gdb ... just in case this is not familiar to you. gdb /usr/sbin/openvpn [gdb info message...blablabla...] (gdb) run --config <your config file> [--other-arguments-you-might-pass] [wait for the crash] (gdb) bt [full backtrace should appear] If you're having troubles, you can grab me on IRC (FreeNode, chat.freenode.net) on the #openvpn-devel channel. We're a few people there most of the daytime (UTC+1). kind regards, David Sommerseth -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org/ iEYEARECAAYFAkuC/ckACgkQDC186MBRfrrktgCggiyiwxI/+EtoI4R8zpzzI1Ce 3B4AnjNqn61Vtip5ZHweNE3Vf0RNWYMm =fqW1 -----END PGP SIGNATURE-----
