Intermittent 52x errors behind Cloudflare that look like origin connection pool exhaustion
An application behind Cloudflare's proxy shows intermittent failures that resemble connection pool exhaustion at the origin, but the origin's pool metrics do not clearly confirm saturation during the affected windows. The goal is to isolate one unresolved behavior: whether the intermittence is caused by Cloudflare's edge keep-alive reuse racing the origin's
