From 8efd2d00dfc921483bbe9c8ffcb62c7932ac29ca Mon Sep 17 00:00:00 2001 From: kisfenyo Date: Tue, 22 Sep 2026 18:04:49 +0200 Subject: [PATCH] romm OOM storm on demo-hp: fixed, measured, closed (R-635) Found because the operator heard the fans. romm 5.3.0 was promoted that morning; the update read `done` and the app ran clean for two hours, then OOM-crash-looped for six - 4530 worker SIGKILLs, ~500% CPU, host load 5.2 while otherwise idle, and nothing alarmed. Raising the limit to 768M was still a guess and fixed nothing (memory.peak hit exactly 768 MiB). Measured instead: ~216 MiB per warm uvicorn worker, so the image's default of 4 workers needs ~882 MiB. /init reads WEB_SERVER_CONCURRENCY; set to 2. Proven under load, not just at idle: 26,645 requests over 300 s, memory 416-614 MiB against 768, trending down, zero SIGKILLs, OOMKilled false. Idle CPU 500% -> 1.64%. The first soak measured nothing - it was pointed at the scratch-guest subdomain, every request 404'd at traefik in 9 ms, and the counter reported 14,026 successes. Positive and negative controls are now asserted before any load is driven. Carried into R-462: `proven` has meant "the update applied and the data survived", not "the new version runs".

It is a record of what the catalog's update promise currently rests on: **for 28 of 53 apps, nothing.** **The list is the nightly rotation's queue**, smallest and least stateful first; `paperless-ngx` should be early because R-630 needs a live reading from it anyway, and `crafty-controller`, `mealie` and `uptime-kuma` should be early because R-631 needs one from each.

Full record: `audits/DRILL-the-28-2026-09-22.md`. | **CLOSED 2026-09-22 — all 28 walked in one night; the findings live in R-630, R-633, R-634** | | **R-633** | **[P2-MEDIUM] A remove sent while a restore is still running reports success, deletes the app's record, and leaves a container restarting forever with a live public route.** MEASURED 2026-09-22 on guest 9202, controller v0.261.0, during the twenty-eight walk. `gokapi` was restored from its own local copy at 11:34:07 and removed at 11:34:22. `POST /backup/restore` answers **302 and works in the background**; the remove tore down what existed and the restore's own `compose up` then RE-CREATED the container at **11:34:24**. **Both calls returned success.** Twenty-five minutes later: `GET /api/stacks/gokapi` reads **`deployed: false`**, and `docker ps -a` shows `gokapi` **`Restarting (1)`** with `RestartCount` climbing, carrying its full traefik label set — including `traefik.http.routers.gokapi.rule: Host(`.enkisfelhom.hu`)`, **a rule with an empty subdomain**, because the deploy values that filled it were deleted with the app. Its own log loops *„Salt for admin password invalid, generating new salt… password does not appear to be a SHA-1 hash"* — the volume holding its config was removed correctly, so the binary can never start. **WHY THIS IS A ROW AND NOT A HARNESS ARTEFACT:** a household can press exactly these two buttons in exactly this order, the product accepted both, and **the remove reported success while leaving the orphan**. Presence of a success message is not evidence of a result. **WHAT IT COSTS:** an app the household believes is gone keeps a container in a restart loop, keeps a route registered on the public reverse proxy, and is invisible to every product surface because the controller no longer records the stack. Nothing in the alarm ladder fires: `08` §4 keys on stacks the controller KNOWS about. **This is R-626's class with the mechanism finally visible** — that row recorded a removed `navidrome` coming back and could not diagnose it because the controller had restarted; here the window is 17 seconds and both halves are in the evidence. **Needs:** the remove path to refuse, or to wait, while a restore for the same stack is in flight — and, either way, to verify the teardown rather than report success without looking. Evidence: `audits/the-28-2026-09-22/apps/gokapi/came-back-evidence.txt`, `apps/gokapi/log.txt`. | **OPEN — P2; owner: CC; product code, so not fixed in this unattended run** | | **R-634** | **[P1-HIGH] An app can be RUNNING, HEALTHY and serving while the controller records it as not deployed — and in that state the household cannot remove it through the product at all.** MEASURED 2026-09-22 on guest 9202, controller v0.261.0, on **two independent apps in one night**: `outline` and `sparkyfitness`. **The controller's own words, in order.** `outline` deploy accepted 11:54:47; **`11:55:51 StopStack outline: current state=deploying deployed=true containers=0`** — a stop while the stack is still deploying; `11:56:09 SaveAppConfig: saving /opt/docker/stacks/outline — 5 env vars, **0 encrypted**, 3 sensitive fields` (the two saves before it both read `3 encrypted`); then **`11:57:16` and `12:02:16 Health probe outline: API GET :3000/_health -> 200`** — the app is up and answering its own health endpoint; and **`12:02:19 StopStack outline: current state=running deployed=false containers=3`**. Three containers, state `running`, health 200, **`deployed=false`**. The remove then answers **`RemoveStack outline: state=not_deployed, deployed=false, orphaned=false, deploying=false` -> `[ERROR] Remove failed for outline: stack "outline" is not deployed`** for BOTH the remove-with-data and the remove-keeping-data call, while `ScanStacks` goes on finding the stack every ten seconds. `app.yaml` survives with `desired_state: stopped` and an **empty `installed_images`**. `sparkyfitness` produced the identical shape 13 minutes earlier. **WHAT THIS COSTS A HOUSEHOLD:** an app that works is invisible to the product as an installation — no badge, no update, no backup selection, and **no way to delete it**; the only exit is a shell. It is the mirror of R-633 (there the record is gone and the container remains; here the container is fine and the record is gone) and it is the **worse** of the two, because the app is serving customer traffic the whole time. **THE MECHANISM IS NOT DIAGNOSED, and this row says so rather than guessing.** What was tried: the controller's full container log for both apps (the sequence above), `app.yaml` on disk, `docker ps -a`, and `GET /api/stacks/`. What was NOT done: reading `runComposeDeploy`'s pin-write path — this was an unattended run and the brief forbade product code. **The one discriminator worth running first:** both apps were walked while two other walks ran concurrently, and `POST /api/backup/run` is box-wide, so a backup or restore for a NEIGHBOURING app was in flight. A serial re-walk is queued tonight; if it reproduces alone, concurrency is not the cause. **A THIRD THING THE SAME LOG SHOWS, recorded here because it is one line away:** at `11:55:57` the health probe dialled **`http://outline-postgres:3000/_health`** — during startup, with the exactly-named container not yet running, `findProbeContainer`'s PREFIX fallback latched onto the POSTGRES sidecar and probed port 3000 on it. Transient, and it resolved once `outline` came up, but it is the same function R-630 is about. Evidence: `audits/the-28-2026-09-22/apps/half-state-outline-sparkyfitness.txt`. **THE SERIAL RE-WALK WAS RUN THE SAME NIGHT AND IT SPLITS THIS ROW IN TWO — recorded here rather than left as the first reading.** Walked again one at a time, with no other walk running: **`outline` deployed normally and removed clean**, and **`crafty-controller` deployed normally, updated `4.10.7 → 4.11.0` to `done`, restored and removed clean.** So for those two the half-state did NOT reproduce alone, and concurrency — a box-wide `POST /api/backup/run` or a restore in flight for a NEIGHBOURING app — is implicated rather than the deploy path itself. **`sparkyfitness` reproduced EXACTLY, alone, in 534 s**: deploy accepted, never reached `deployed` with a pin, `app.yaml` left with `desired_state: stopped` and an empty `installed_images`, and **both remove calls refused with `stack "sparkyfitness" is not deployed`.** **So the row stands, at one reproducible app instead of three, and the honest split is:** (a) `sparkyfitness` has a deploy that does not finish and leaves a record the product cannot clear — reproducible, P1; (b) under concurrent work the same unremovable half-state can be reached by apps that are otherwise fine, which is the more alarming half because those apps were **running, healthy and serving** while recorded as not deployed. **Neither half is diagnosed** — `runComposeDeploy`'s pin write was not read, because the brief forbade product code. | **OPEN — P1; owner: CC; reproducible alone on `sparkyfitness`, concurrency-linked on the other two; next step is `runComposeDeploy`'s pin write** | +| **R-635** | **[P1-HIGH] `romm 5.3.0` does not fit the memory the template gives it, and the guarded Update called that a success — the app has been OOM-crash-looping on demo-hp for six hours at ~500% CPU.** FOUND 2026-09-22 17:37 **because the operator heard the fans**, which is the only reason it was found at all. `romm` was promoted `5.0.0 -> 5.3.0` on the live catalog that morning (`audits/PROBE-FIX-2026-09-22.md`) after the edge was PROVEN on scratch guest 9202, and the guarded Update was then pressed on demo-hp guest 9201 at **09:08:22Z**, reaching **`done` in 74.8 s** with the app `running`. **It ran clean for two hours.** The first worker kill is at **11:09:20Z**; by 15:38Z there had been **4,530** of them — `Worker (pid:…) was sent SIGKILL! Perhaps out of memory?` — with `docker inspect` reading **`OOMKilled: true`**, the container pinned at **457 MiB of its 512 MiB limit**, and `docker stats` showing **499.51% CPU**. The host's load average sat at **5.2 while otherwise idle**. `rq_cron` is killed and restarted every few seconds in a permanent storm. **THREE THINGS THIS ESTABLISHES, and the third is the one that changes how promotions are judged.** (1) The template's own comment says *`RAM: ~300MB (mem_limit: 1024M total — romm 512M + mariadb 384M + redis 128M)`*; **5.3.0 needs more than 512M and the template was not re-sized when the version moved.** A version move is not only an `image:` line. (2) **The update reported `done` and the app reads `running`**, because nginx answers `GET /` with 200 while the gunicorn workers behind it are being killed — a THIRD variant of the R-618/R-630 theme: the probe is right, the port is right, and the answer is still a false green. (3) **NOTHING ALARMED.** Docker OOM signals are silent in LXC guests (the `lxc-docker-oom-signals-unreliable` finding, R-528), `08` §4 does not treat a running-but-thrashing app as down, and the box is `hub.enabled: true` — so six hours of a machine at 500% CPU produced no event and no mail. **The detector that worked was a person in the room.** **AND THE LESSON FOR R-462's METHOD, which is the real cost:** every `proven` verdict in the update night and in the twenty-eight measures the app for the **minutes of the walk**, not for a day of running. `romm` passed its walk, was seeded, read back and restored — and broke two hours later. **`proven` currently means "the update applied and the data survived", NOT "the new version runs".** Needs: decide between rolling the catalog back to 5.0.0 and raising romm's `mem_limit` (measured, not guessed); and a soak longer than a walk before any future promotion. **FIXED AND MEASURED 2026-09-22, in two steps, and the FIRST step was still a guess.** *Step 1 (operator's choice):* the limit was raised 512M → **768M** (`app-catalog-felhom.eu@886956d`). It slowed the kills from ~12/min to ~7/min and **stopped nothing** — 37 SIGKILLs in five minutes, `OOMKilled` still true, and the cgroup's own `memory.peak` read **exactly 768 MiB**: it hit the new ceiling and died there. *Step 2, from a MEASUREMENT instead:* the per-process RSS inside the container reads **~216 MiB per warm uvicorn worker**, so the image's default of four workers plus the master needs **~882 MiB** before nginx and the job runner — more than any sensible limit for this box. **The lever was in the image all along:** `/init:143` runs `--workers "${WEB_SERVER_CONCURRENCY:-4}"`. **Four workers is a SERVER default on an appliance serving one household.** Setting **`WEB_SERVER_CONCURRENCY=2`** (`app-catalog-felhom.eu@f4eb94f`, limit left at 768M) and applying it through the product's own Update button fixed it. **PROVEN UNDER LOAD, not just at idle:** 6 concurrent callers driven at romm through the household's own route for 300 s — **26,645 requests** (9,687 × 200, 16,958 × 401 on the auth-gated endpoints), CPU a steady **~200%** (exactly two workers saturated, by design), memory oscillating **416–614 MiB against the 768 MiB limit and trending DOWN**, and **zero** SIGKILLs, `OOMKilled: false`, `RestartCount: 0` throughout. At idle afterwards: **1.64% CPU**, 610 MiB, host load falling from 5.2 to 2.4. **AND THE FIRST SOAK MEASURED NOTHING, which is worth more than the second one:** it was pointed at `arcade.enkisfelhom.hu` — the scratch-guest fixture's default subdomain — while this box deployed romm at `jatek`. Every request 404'd at traefik in 9 ms, romm sat idle at 0.64% CPU, and the counter cheerfully reported **14,026 successful requests**. It was caught only because 0.64% CPU under load is not believable. **A positive AND a negative control are now asserted before any load is driven** (`jatek` must not 404; a nonsense host must). R-96 rule 3, in a new surface. **WHAT STAYS OPEN, and it is the part that outlives romm:** 610 MiB of 768 MiB is **79%** — it works with ~158 MiB of headroom and the soak never exceeded 614 MiB, but it is not generous, and nothing watches it. **And the method lesson for R-462:** a version move is not only an `image:` line — the new version's SHAPE (worker counts, per-worker footprint) has to be measured too, and a walk lasting minutes cannot see a ceiling reached in two hours. Every `proven` verdict in the update night and in the twenty-eight means *"the update applied and the data survived"*, **not** *"the new version runs"*. Evidence: `audits/probe-fix-2026-09-22/romm-soak.json`, `romm-soak.out`. | **CLOSED 2026-09-22 — two workers, 768M, proven under 26,645 requests; the 79% headroom and the `proven`-means-minutes lesson are carried into R-462** |
