  "definition": "Credit starvation is a transmission stall in which a Fibre Channel sender has a frame ready but no available buffer-to-buffer credit.",
  "note": "An idle zero-credit snapshot does not establish a stall. Keep event counts separate from time spent waiting and inspect both link directions. [credits]\n\nStarvation describes an observation, not its cause; it does not establish cyclic buffer deadlock. See the worked credit-window examples on the companion technology card.
