rsshub.app was returning non-2xx responses (likely 429 rate-limit) which were never cached, causing a thundering herd: 874 requests in 5 minutes to the same URL instead of 1. The in-flight dedup also cascaded — when waiters woke up and found no cache, they started their own fetches. - Cache all RSS responses (non-2xx with 60s TTL vs 5min for success) - Dedup waiters serve 502 on failure instead of cascading to new fetches - Log upstream error status codes for future diagnosis - Raise memory cleanup threshold to 450MB, only clear OpenSky cache
