+## immich: the database gets 768M, and v3.2.4 is published with it (2026-09-30, afternoon, R-732)
+
+- **Cause, measured** (`felhom.eu/documentation/audits/immich-first-start-2026-09-30/A-cause.md`): 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). At 512M without swap: 61–104 OOM kills; with swap it survives by swapping. `shared_buffers` 128MB
+  alone does not help (measured). An update that ships a new geodata file re-runs the import.
+- `56c4888`: immich v3.2.2 → v3.2.4 (server + ML), `immich-postgres` 512M → 768M, `mem_limit` 4096M → 4480M, header comment
+  corrected. Proven with swap off: fresh installs (bench ×2, 9202) 0 kills, anon ≤ 54 %; the step on both venues.
+  The step carries `files_may_change` (immich's `.immich` markers; R-734). +256 MB per immich box.

 ## The last six PostgreSQL apps decided; seven more apps update themselves at night (2026-09-30, day brief)

-- rallly, outline, sparkyfitness → PostgreSQL 18: bench converted (31/42/94 tables equal), box 9202 CONVERTED in 7.1/7.9/9.8 s
-  through the guarded Update, one undo case each (undone, back on the old major, seed read back). Engine gate ALLOWED on push.
-- zipline, adventurelog, immich stay on 16 (their upstreams run 16, 16, 14).
-- Three new front-door fixtures; zipline's fixture fixed to its real first-run route.
-- Part F: bookstack, kimai, audiobookshelf, n8n, navidrome, grafana, komga — each proven on both venues, one commit each.
-- immich v3.2.4 NOT moved: first start at today's pin OOM-killed its database on the bench (R-732).
-- Night-updatable apps: 28 (+ nextcloud) in the morning → 31 (+ nextcloud) after.
+- Cause: 9 concurrent geodata INSERTs need ~575 MB in the database; 512M only fits with swap. Controls: swap alone, limit alone
+  flip it; shared_buffers alone does not.
+- `56c4888`: v3.2.4 + `immich-postgres` 768M (`mem_limit` 4480M). Fresh installs with swap off: 0 kills on both venues.
+- The step: bench proven (10-min watch 0 kills), box 9202 done in 58.5 s, album read back, limit 768M after.
+- An installed immich on 3.2.2 gets 768M with its next guarded Update (by hand, or the night leg when a whole copy exists).
