That's kind of hysterical given how much RAC costs. Sort of defeats the entire point, doesn't it?

Given where the client-side storage option is likely headed wrt timeouts, given the way apps have to be built to essentially ignore timeouts, and given that timeouts are just plain stupid for the most part, I think it would be within the realm of sanity to enhance the cache to optionally ignore errors during last-access touch attempts. That's assuming it doesn't already, but I don't recall.
