TransferManager#downloadFile — upstream 503 (자동 복구됨)
What Happened#
2026-06-08 14:00 KST, cupixworks-capture-3dreconstruction-instance 에이전트(capture 708636)가 capture에 속한 영상 파일(VID_20260605_153312_00_292.insv, video id 668420)을 다운로드하던 중 TLS 소켓이 서버 측에서 끊기는 ECONNRESET(Node.js: Error: aborted)이 6회 연속 발생했다. TransferManager의 retry 정책(MaxRetries=5)이 모두 소진되어 failTask로 종료되었고, 최상위 Promise rejection이 aborted라는 단어 하나로만 캡처되어 fingerprint된 클러스터다.

Affected Teams#
| Team / Domain | Error Count | Impact |
|---|---|---|
| gad / 3D reconstruction agent | 1 cluster (6 download attempts + 1 failTask) | 단일 capture(708636)의 3D reconstruction job 실패 — 해당 capture의 mesh/pointcloud 결과 미산출 |
