# Shift Handoff Notes
**Incident:** Critical CPU spike on claw-gateway1 (96% usage, +28.8% upward trend)
• **What Happened:** P1 alert triggered at 16:03 UTC on 2026-04-27. AI Infra Monitor detected runaway CPU on single gateway host with risk of service degradation.
• **What Was Done:** Engineer took manual control at 16:03:27 UTC. Issue was investigated and resolved within 42 seconds (16:03:47 UTC). Root cause likely: runaway gunicorn worker, monitoring loop, or resource contention spike.
• **Current State:** RESOLVED. Host CPU has normalized. All ADOStack services (gunicorn, ai-infra-monitor, rag-runbook-assistant, oncall-assistant) confirmed operational.
• **Watch For:** Monitor claw-gateway1 CPU trends over next 2-4 hours for recurrence. If spike returns, SSH to host and run `ps aux --sort=-%cpu | head -20` to identify problematic process. Check service logs for errors.
• **No Follow-up Required:** This was a transient spike. No infrastructure changes needed at this time.
