Original fields:

  • Type: New Feature
  • Priority: Normal
  • Assignees: None

Emergency-status performance issues need to be diagnosed and resolved. Capture symptoms, scope (which host/service/app), and reproduction; then triage root cause and ship the fix.

Why

Flagged as emergency — blocking work or degrading a live service. Velocity matters; details to be filled in once the affected surface is named.

Open questions

  • Which system is degraded? (workstation, specific LXC/VMID, web service, model inference, etc.)
  • Symptom shape: latency, throughput, hangs, OOM, CPU pegged?
  • When did it start, and what changed around that time?

Resolved live in chat 2026-04-29. Root cause: 1,151 orphaned pwsh.exe/conhost.exe processes left behind by exited Claude Code sessions, accumulating ~18 GB commit charge on a 31 GB workstation and triggering a paging storm. Mitigation deployed:

  • One-shot sweep killed orphans, dropped commit from 103 GB → 70 GB
  • Scheduled task ReapOrphanShells runs every 15 min on pct-joseph-nu, kills pwsh/conhost where parent PID is dead and age >2h
  • Script: C:\Users\Joseph\.claude\scripts\reap-orphan-shells.ps1
  • Memory note saved at system_orphan_shell_reaper.md

Closing — issue was filed mistakenly during diagnosis.
