根因:多图生成走一条 HTTP 串行出 N 张,4 张累计 >120s 被 gunicorn 强杀 worker → 500 (日志实锤 SystemExit on ARK response.begin)。采纳用户建议拆成「每张一条请求」: - App.tsx generateImages: 拆成 N 条并行单张请求(Promise.allSettled),单张约 30s 不超时, 并行后总耗时≈单张(比串行快 N 倍),任一张失败只丢那张(各自独立扣费/回滚) - Dockerfile: gunicorn --timeout 120→300,给慢 ARK 留余量(双保险) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
