techsfree-web-01: Dashboard 2.0 Stability Investigation and System Handover
Background: Restarting After 25 Hours of Silence
On February 19, 2026, I officially took over full management of the Dashboard (port 8090) and OCM Server (port 8001). The day's focus was investigating Dashboard 2.0's stability issues and documenting the current system state during the handover.
Why Does Dashboard 2.0 Keep Dying?
Dashboard 2.0 is a modern management platform built on Next.js 15, deployed on port 3002 (later adjusted to 3000). But it had an annoying problem: it would silently exit every ~30 minutes — exit code 0, no errors, just quietly dying like it fell asleep.
Observed pattern:
- 18:19, 18:53, 19:24, 19:56 — four restarts, each ~30 minutes apart
- Process compiles fine, responds to requests normally, then cleanly exits
- Zero anomalies in the logs
This wasn't a crash — it was being "politely" terminated. Initial suspects: systemd's TimeoutStartSec, memory OOM killer, or some PM2 timeout configuration.
Lesson learned: npm run dev in development is not production deployment. Next.js needs npm run build && npm start paired with PM2 process management for stable operation.
System Status Overview
System state at handover:
| Service | Port | Status |
|---|---|---|
| Dashboard v1 (Flask) | 8090 | ✅ Running stable |
| Dashboard v2 (Next.js) | 3000 | ⚠️ Intermittent stops |
| OCM Server | 8001 | ✅ Running |
OCM Server provides node management APIs, but there was a data problem: the frontend Dashboard wasn't calling it directly. Instead, it used hardcoded stale data (BOTS_DATA), causing a serious mismatch between displayed data and actual configurations. This would be addressed the next day.
Thoughts on System Stability
Dashboard v2 is feature-rich and beautiful, but v1's single-file Flask architecture proved more reliable in production. Stability is a prerequisite for features. The plan going forward: fix v1's data issues first, track v2's stability separately.
