 `bookva-es` → `ES_JAVA_OPTS=-Xms512m -Xmx512m` → `-Xms256m -Xmx256m`.
 Сделано: Portainer PUT стека 37 (`PUT /api/stacks/37?endpointId=1` с реконструированным compose). Verify: `docker logs bookva-es | grep heap` → `heap size [256mb]`.
 
+### 4. `minio` / `bookva-minio` / `books-ops-mcp` — cgroup-потолки памяти
+Реконструкция compose вслепую рискованна (данные minio-тома, files-секреты, сеть) → `docker update --memory` (без пересоздания):
+```bash
+docker update --memory 512m --memory-swap 512m minio
+ docker update --memory 384m --memory-swap 384m bookva-minio
+# books-ops-mcp (Node) — 'memory.memsw.limit_in_bytes: device or resource busy' (cgroup v1) — не применилось.
+```
+Потолки (защита от раздувания в пик; не освобождают текущие буферы).

 ## Verify / smoke
 
 - `free -m` — free растёт, swap падает (mongo cache_size=256M).
