If the SA is up, it will stay up without interesting traffic until the lifetimes expire. The only reason a tunnel comes down with no interesting traffic is that the lifetimes expire, and because there's no traffic, a new one is not built. They're not actually torn down in the middle of a lifetime because of no inteesting traffic
Just increase your lifetimes to the max and you should be fine. They will eventually come down, but at least it'll be every few days instead of every day.
