ChildProcessManager::setupEventHandlers | Child process stderr: 15: 0x12c1b3b [/usr/bin/node]

What Happened#

2026-07-21 21:00:39 KST, cupixworks-any-bimrevision-agent 서비스에서 BIM comparison 자식 프로세스가 V8 heap OOM 으로 SIGABRT 종료됐다. 부모 프로세스의 ChildProcessManager 가 자식 stderr 를 라인 단위로 로거에 그대로 전달하는 구조이기 때문에, V8 이 crash 시 출력하는 native stack trace 한 줄 한 줄이 각각 별도의 error 로그로 쪼개져 25개의 유사 클러스터로 fingerprint 되었다. 이 클러스터(eecaced6)는 그 stack trace 중 15번 프레임(0x12c1b3b [/usr/bin/node]) 하나에 해당한다.
