ChildProcessManager::setupEventHandlers | Child process stderr: 1: 0xb78db3 node::OOMErrorHandler(c

What Happened#

BIM revision agent(cupixworks-any-bimrevision-agent)의 BimCompareProcess 자식 프로세스가 bim_id=17216 리비전 비교(V4→V5, 총 211,677 elements) 실행 중 V8 힙 상한(≈8GB)에 도달해 FATAL ERROR: Ineffective mark-compacts near heap limit 로 종료되었다. 부모 프로세스는 자식의 stderr 스트림을 그대로 error 레벨로 로깅했고(ChildProcessManager::setupEventHandlers | Child process stderr: ...), 이후 자식이 SIGABRT 로 죽자 BimRevisionService::run 이 실패로 종료했다. 총 25개의 에러 클러스터가 동일 시각에 발생했으며 이 파일은 그중 OOM 헤더 라인 하나에 해당한다.
