ChildProcessManager::setupEventHandlers | Child process exited

What Happened#

2026-06-24 23:52 KST에 cupixworks-capture-refinement-arm-instance 서비스가 capture refinement job 1149542를 실행하던 중, 자식 프로세스로 분리된 scenemapper.process가 native C++ 라이브러리(scenemapper_api.node) 내에서 SIGSEGV로 강제 종료되었다. 부모의 ChildProcessManager는 child의 exit/close 이벤트를 받아 두 줄의 error 로그를 남겼고, refinement job은 그대로 실패 처리되었다. 동일 패턴은 14일 윈도우에서 24회 이상 반복되고 있는 만성 결함이다.
