i believe that this is an easy question. i have a pix with multiple ipsec tunnels. whenever i attempt to work on one of the tunnels the pix hangs and i have to reboot. i believe there is a command but i can't remember it or find it, that turns off all of the ipsec tunnels while i make some modifications and then re-enable it. i am thinking that it is something like clear crypto map or something like it and then you re-configure the map.
let me know if someone remembers what the command is
