gates / gates (push) Successful in 27s
- R-732: the first-start geodata import runs up to 9 concurrent 5000-row INSERTs; the database needs ~400 MB anon + ~170 MB touched shared_buffers (the image's FIXED 512MB, not host-RAM sizing). 512M fits only with swap (bench swap 0: 61-104 kills; 9202 swap 512 MiB: survived by swapping). Controls: swap alone, limit alone flip it; shared_buffers 128MB alone does not. Catalog 56c4888: v3.2.4 + 768M, proven with swap off on both venues. audits/immich-first-start-2026-09-30/A-cause.md. - R-730: scripts/iso/build-felhom-iso.sh refuses an uncommitted/untracked/unpushed tree (no bypass), records repo-commit from the gate and iso-v<version>; test iso/test/clean-tree.sh, red-proof run (status check removed -> 2 of 4 cases fail -> restored). - R-731 narrowed (gitea 28.0.0 GA; mariadb 13.0 a short-term Rolling line). R-676 note. - New rows R-733 (bench has no swap, boxes 512 MiB), R-734 (immich .immich markers -> files_may_change). - STATUS: the golden line corrected (no bake is due; 0.283.1 is the newest release). Register 364 -> 366. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0159rPz1ZhFKsS53msqPYxtS

# REPORT — 2026-09-30 (late afternoon): immich's first start, the cause and the fix; STATUS golden line; R-730, R-731
|
||
|
||
| part | outcome | why / where |
|
||
|---|---|---|
|
||
| A cause | **done** — up to 9 concurrent geodata INSERTs need ~400 MB anon + ~170 MB touched shared_buffers; 512M fits only with swap. Control pair: swap alone → pass, limit alone → pass, `shared_buffers` alone → still killed | `audits/immich-first-start-2026-09-30/A-cause.md` |
|
||
| B fix + proof | **done** — catalog `56c4888`: v3.2.4 + `immich-postgres` 768M, `mem_limit` 4480M. Fresh installs, swap OFF: bench ×2 and 9202, 0 kills, anon ≤ 54 %. Step: bench proven (10-min watch, 0 kills), box done 58.5 s, read back, running limit 768M | `bench/`, `box/` |
|
||
| C STATUS + register | **done** — the golden line corrected; R-732 closed | `STATUS.md` |
|
||
| D1 R-730 | **done** — the ISO build refuses a dirty/unpushed tree; red-proof run; `iso-v<version>` | `scripts/iso/test/clean-tree.sh` |
|
||
| D2 R-731 | **done (narrowed)** — gitea 28.0.0 is GA; mariadb 13.0 is a short-term line; the standing shape-switch control NOT built | `D/D2-release-checks.txt` |
|
||
|
||
No controller, agent or hub release. No bake (none is due).
|
||
|
||
## Claims in the brief, checked
|
||
|
||
- **"the limit is 512M and the header says 256M"** — right (and `mem_limit` 4096M was already 128 MB under the sum of the four limits).
|
||
- **"no `shm_size`"** — right; `/dev/shm` 64M, 1.1M used — not involved, so none was added.
|
||
- **"the image sizes memory from host RAM"** — **wrong**: `shared_buffers` 512MB and `work_mem` 16MB are FIXED in the image's own
|
||
`postgresql.conf`; the rest are PostgreSQL defaults.
|
||
- **"bench and box differ by host RAM"** — **wrong**: both on demo-hp. They differ by **swap** (box 512 MiB, bench 0), proven by giving
|
||
the bench swap alone.
|
||
- **"no bake is due"** — right (the gate: `newest golden baked 0.283.1`, OK).
|
||
- **"the fix reaches installed apps only through the v3.2.4 step"** — right, and more: the step itself RE-RUNS the geodata import
|
||
(228 294 → 228 571 places), so publishing v3.2.4 without the fix would have killed the database during the update.
|
||
|
||
## Per-box cost
|
||
|
||
**+256 MB** on immich's database limit (512M → 768M); the declared `mem_limit` goes 4096M → 4480M (+384, of which 128 corrects an
|
||
old undercount). Only boxes with immich.
|
||
|
||
## What an installed immich gets, and when
|
||
|
||
An immich on 3.2.2 keeps 512M until its next guarded Update, which moves it to v3.2.4 with 768M in one step (measured on 9202:
|
||
running limit 805306368 after). The night leg takes that step only when a fresh whole copy exists (the step carries
|
||
`files_may_change` — R-734); otherwise the household's button does. A 3.2.2 immich's own first start is already behind it.
|
||
|
||
## Rows
|
||
|
||
Register **364 → 366**. Closed: R-732, R-730. Narrowed: R-731. Notes: R-676. Opened: **R-733** (the bench has no swap, the boxes
|
||
do; a customer guest's swap is not recorded), **R-734** (immich's `.immich` markers set `files_may_change`).
|
||
|
||
## Teardown (three layers)
|
||
|
||
- **Machine:** 9202 — immich removed through the product (no volume left; its drive folder kept by R-442's refusal, as before),
|
||
`controller.yaml` restored (live catalog, read back), swap back at 512 MiB (it was 0 for the one fresh-install proof).
|
||
- **Host:** bench LXC 9401 destroyed, template removed, host temp files removed; drill repo reset to the live `main` (`56c4888`),
|
||
image lines identical.
|
||
- **Hub:** not touched.
