I am of the simple-minded, low-tech approach school. Does "rebooting" consist of some sort of power-down-power-up?

If so, get a timer that shuts off power at some specific time each week for some specified period of time.

This one will do nicely. 30A should be able to handle the load in any case. Set it for 3:00 am of a Tuesday night and see how it goes. Unless some of your customers are running SETI, they should never know.
