Matt Bruce b934c9fdb3 Task #7: Root cause analysis - why websites die 
- Analyzed system limits, memory usage, process status
- Identified primary suspect: Next.js dev server memory leaks
- Secondary suspects: macOS power mgmt, SSH timeout, OOM killer
- Created monitoring script for CPU/memory/file descriptors
- Documented recommendations: production builds, PM2, nohup

Project Hub Tasks Created

User added 3 new tasks to track progress on OpenClaw infrastructure:

  1. Task #4: Redesign Heartbeat Monitor to match UptimeRobot (Priority: High)

    • Study https://uptimerobot.com design
    • Match look, feel, style exactly
    • Modern dashboard, status pages, uptime charts

  2. Task #5: Fix Blog Backup links to be clickable (Priority: Medium)

    • Currently links are text-only requiring copy-paste
    • Different format for Telegram vs Blog

  3. Task #6: Fix monitoring schedule - sites are down (Priority: Urgent)

    • 2 of 3 websites down
    • Cron job not auto-restarting properly

Critical Incident: All 3 Sites Down (~2:13 PM)

  • gantt-board (3000): DOWN
  • blog-backup (3003): DOWN
  • heartbeat-monitor (3005): DOWN

Root Cause: Cron job wasn't properly killing old processes before restart, causing EADDRINUSE errors.

Resolution:

  • Manually restarted all 3 sites at 14:19
  • Updated cron job with pkill -f "port XXXX" cleanup before restart
  • Added 2-second delay after kill to ensure port release
  • Created backup script: monitor-restart.sh
  • Task #6 marked as DONE

System Health (2:30 PM)

All 3 sites running stable after fix.

New Task Created (2:32 PM)

Task #7: Investigate root cause - why are websites dying?

  • Type: Research
  • Priority: High
  • Added to Project Hub Kanban board
  • User wants to know what's actually killing the servers, not just restart them
  • Suspects: memory leaks, file watchers, SSH timeout, power management, OOM killer

New Task Created (2:35 PM)

Task #8: Fix Kanban board - dynamic sync without hard refresh

  • Type: Task
  • Priority: Medium
  • Board uses localStorage which requires hard refresh to see updates
  • Need server-side storage or sync mechanism for normal refresh updates
