Restart specific racoon tunnel

I have several **gif*** interfaces on my FreeBSD box. They are representing tunnels, encrypted using racoon+ipsec. If, at some moment, one of the tunnels hangs up, I am forced to reset racoon this way: /usr/local/etc/rc.d/racoon restart But in that case all tunnels are reset, which leads to a short absence of connectivity on all my tunnels (3-5 seconds, but nevertheless). Is there any method to reset one specific gif tunnel, while not touching any other tunnels?
