ZGaetano 3c7cc1a77f fix(worker): retry transient S3 aborts + reuse one keep-alive client ... Burn test: 5 assets errored during proxy with 'aborted'/'socket hang up' during the master DOWNLOAD. The masters all exist in S3 (262-269MB) — it's the connection-limited RustFS backend dropping streams when 8 jobs hammer it at once. Two fixes: 1. downloadFromS3/uploadToS3 now retry transient failures (aborted, socket hang up, ECONNRESET, timeout, 5xx, throttle) up to 5x with exponential backoff, cleaning the partial file between download attempts. A single mid-stream abort no longer errors the whole asset. 2. Reuse ONE shared S3 client instead of createS3Client()+client.destroy() per call. The per-call destroy tore down the keep-alive agent's sockets every time, so connection pooling never happened and each transfer opened fresh connections — exactly what overwhelmed RustFS. A long-lived client lets the keep-alive pool actually be reused.		2026-06-04 16:56:11 +00:00
