Hi guys, What is considered a process failure? I.e., starting at what moment since the start of the first unsuccessful communication attempt with this process is it considered dead? Asking because we see some big machines having transient link failures that may appear as node failures for a spell. Will user controllable timeouts be sufficient to define a process failure? Best regards.
