-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 If it isn't actually alive anymore, it won't be able to serve requests, and by the same token won't be able to maintain its matrix of producers and consumers. Once that state is reached, the system goes into a "fail-safe" mode. Sure, fail-safe mechanisms can fail.

Your missing what I said. What if the cache continues sending WCCP packets, but the cache itself has died?
i don't think i am -- i would assume that the cache design would perform suitable sanity checks prior to sending out a heartbeat. if the design is sound, the cache would not be capable of sending out WCCP packets if it has 'died' in some way.
You can't be serious.
A cache may check itself, but my arguement is that this self-checking scheme may fail, seeing itself as alive, but not able to actually serve requests.
