--- Comment #2 from Gert Doering <gert@greenie.muc.de> ---
"openvpn[99009]: Unknown kernel notification 2"

would be an OVPN_NOTIF_FLOAT - which is something 2.6 does not expect.  With
openvpn-devel this should be fine, and I can see that we can backport commit
b66b80b2ab7 ("dco: support float notifications on FreeBSD") to 2.6

I'm not sure why you would see this by making the client reconnect - every new
connect should receive a new peer-id and thus not trigger a float event.

Can you try with openvpn-devel (2.7_alpha3) and see what it will log in this
case?
