> Currently, a single exception from the StateStore will cripple a router by
> clearing the caches before the replacement is loaded. Since the routers have
> the information in an in-memory cache, it is better to keep running. There is
> still the timeout that will push the router into safe-mode if it can't load
> the state store over a longer period of time.
