Cache Instance Failure Incident Analysis and Root Cause Investigation

During a night‑time outage, a XCache (Codis + Pika) instance hung due to massive write load triggering low‑level protection, causing Sentinel to switch masters; the proxy’s accept queue filled with timed‑out sockets, blocking new connections, so scaling the proxy layer and expanding capacity restored service while prompting automation, health‑check, and queue‑overflow alerts.
