AWS SQS TLS handshake failure — transient network degradation

What Happened#

2026-07-18 18:15:59 KST 에 cupixworks-capture-postprocessor-agent 가 ap-southeast-2 리전 SQS 큐로 DeleteMessage 호출을 시도하다 AWS SDK 의 재시도 예산을 소진한 뒤 socket hang up 으로 최종 실패했다. 동일 시간대에 ap-southeast-2 SQS 엔드포인트 IP 로 향하는 ECONNRESET 이 반복적으로 관측되었고, 다음 메시지 사이클(약 13초 뒤)부터는 정상 회복되어 단발성 리전 네트워크 flap 로 판단된다. 영향은 SQS 메시지 1건 삭제 실패로, ApproximateReceiveCount 재수신을 통해 재시도되거나 MaxReceiveCount 도달 시 DLQ 로 이동한다.

Quick Facts#

Field Value
exception.class socket hang up (Node.js http agent — AWS SDK v2 wrapped)
exception.message `AwsQueueManager::deleteMessage
top_frame packages/base/src/manager/aws-queue.manager.ts:99
runtime Node.js / aws-sdk v2 (AWS.SQS, apiVersion 2012-11-05)
env production, ap-southeast-2

Affected Teams#

Team / Domain Error Count Impact
scs-assetfuture / cupixworks-capture-postprocessor-agent 1 SQS delete 실패 1건. 메시지가 visibility timeout 후 재수신되어 postprocessing 이 중복 실행될 위험 (idempotency 로 완화)
