Tower Health Report — 2026-09-16

1. Gateway Lifecycle — 1 Sep to 16 Sep

Each bar = one gateway process lifetime. Green = clean exit, red = unclean (SIGKILL/OOM/VM death), amber = signal-initiated.

Key Error Details

Time (UTC)	Severity	Source	Message
00:58:41	Error	Provider	OpenRouter payment/credit error — `OPENROUTER_API_KEY` not set. MOA aggregator fallback fails 3/3 retries. Session `20260916_005710_a261ff` fails.

02:05:44	Error	Discord	Delivery to `discord:1531750964124455073` failed: 429 Rate Limited. retry_after=0.3s.
02:09:08	Error	Provider	Nous API 401: "Your API key is invalid, blocked or out of funds." → `portal.nousresearch.com`
02:09:23	Warning	Info	Defunct Hermes process found: PID 9580, started Sep 7 06:10, elapsed 8d 19h 58m (zombie).
02:56:28	Warning	TUI	TUI parent received SIGHUP → killed gateway (graceful-exit-cleanup).

03:29:31	Warning	Gateway	Previous gateway (pid 7991) exited UNCLEANLY — no exit path ran. SIGKILL/OOM/VM death suspected. Last heartbeat 03:27:46.
03:33:34	Info	Gateway	SIGTERM from s6-supervise → clean shutdown in 0.44s → immediate restart (pid 152).
03:43:54	Warning	Discord	Slash command sync timed out — Discord rate-limit bucket saturated.
04:13:07	Error	Discord	Failed to edit message 1549634193519149169: 503 Service Unavailable. Transport failure: immediate connect error.
04:21:30	Warning	Write-safe	`write_file` denied: `/opt/hermes/web/src/lib/download.ts` outside write-safe root. (iOS Safari download fix attempt.)
04:30:06	Warning	Cron	Cron job a69759413e81: p5js skill missing again. Job proceeds with solar-pro4:free anyway.

3. Cron Job Health

Root cause: The p5js skill is listed in the cron job's skill requirements but is not installed in the skills directory. The job falls back to solar-pro4:free and still produces a text report, but any graphics/charts the p5js skill was supposed to generate are lost.

What the job does produce: A text summary of tower uptime is generated and sent to Discord (when not rate-limited). The 04:30 UTC run on Sep 16 did execute — it's the p5js graphics that are missing.

Defunct Process

PID	Started	Elapsed	State	Note
9580	Sep 7 06:10	8d 19h 58m	Zombie (Zs)	Parent PID 123. Discovered during terminal tool run at 02:09:23. Likely a stale agent subprocess that never reaped.

4. LLM Provider Status

Aux Provider: OpenRouter

Status	Issue
Unhealthy	`OPENROUTER_API_KEY` not set in environment. Marked unhealthy for 60s intervals. MOA aggregator task fails when OpenRouter is requested.

Impact: The MOA (Mixture of Agents) aggregator falls back to OpenRouter when configured. Without the key, any session that triggers MOA aggregation fails entirely (3 retries, then error). The cron job and current Discord session use direct Nous calls instead, so they work.

5. Memory & Resource Snapshot

From last heartbeat of killed gateway (pid 7991) and current housekeeping logs.

OOM suspected

No

The killed gateway (pid 7991) had RSS 381 MB with 45 GB available — no evidence of OOM. The unclean kill was more likely a VM restart, host maintenance, or s6-supervise decision. Memory is well within bounds; housekeeping trims fire every ~60s keeping RSS stable.

6. Findings & Recommendations

[S1] Pinned model broken since Sep 7. nemotron-3-ultra-free via opencode-free returns HTTP 400 (OpenCode free-tier rejection). The system correctly falls back to solar-pro4:free, so there's no user impact, but the pinned model config is stale. Either renew the OpenCode credential or remove the pinned model from config.yaml.

[S2] Tower uptime cron job missing p5js skill. The cron job a69759413e81 lists p5js as a required skill. It's not installed → the job warns every run and produces text-only output (no charts). Fix: install the p5js skill, or remove it from the cron job's skill list and accept text-only reports.

[S3] Discord API instability. Three separate Discord incidents in 24h: 429 rate limit on delivery, 503 on message edit, slash command sync timeout. All recovered automatically. If this becomes a pattern, consider reducing message frequency or adding backoff.

[S4] OpenRouter key not configured. OPENROUTER_API_KEY is not set. MOA aggregator sessions fail when they hit the OpenRouter path. If MOA is not needed, remove it from the config. If it is needed, add the key via hermes setup.

[S5] Unclean gateway kill on Sep 16 03:27. pid 7991 (10d uptime) was killed without an exit path — SIGKILL/OOM/VM death. No OOM evidence (381 MB RSS, 45 GB free). Likely host-level event. The s6-supervise restart chain worked correctly: clean SIGTERM → immediate restart → running now.

[S6] Write-safe root blocking file writes. HERMES_WRITE_SAFE_ROOT=/opt/data blocks writes to /tmp and /opt/hermes/web/src/. This is by design for container safety. The iOS Safari download fix (download.ts) cannot be applied from inside the container — it needs a host-side patch.

[S7] Zombie process PID 9580. Stale agent subprocess from Sep 7, still in zombie state (Zs). Parent PID 123 should reap it. Harmless but worth noting.

[S8] TUI gateway crashes (Sep 2, 3, 16). All three TUI crashes are SIGHUP-driven graceful exits, not hard crashes. The Sep 2 crash log shows a 1220-line stack dump with an encoding error in the signal handler's stack trace formatting — a Python 3.13 linecache issue, not a TUI bug. The TUI is not the primary interface; the Discord gateway is.
