Or plan ahead. If you know you will be changing some lease options you should set the lease time down to something small at least $(current_lease_period) seconds ahead of time. Then you can be fairly certain that all systems will get a new lease within $(new_lease_period) seconds of you change. Afterwards you can increase the lease period back up. Of course, this assumes you were not handing out "infinite" lease periods. -- -- Perfection is just a word I use occasionally with mustard. --Atom Powers--
