Dev Notes
Gui has run into this in a different controller. This is likely to be caused by a race condition on the update of the proxy. Other processes may be changing either the proxy itself, proxy rules, backends or backend usage, and thus causing multiple attempts in parallel to "touch" the proxy, directly or via proxy's affecting_change_history.
