ChildProcessManager::setupEventHandlers | Child process stderr: 9: 0x10ea385 v8::internal::HeapAllo

What Happened#

2026-07-21 21:00:39 KST, cupixworks-any-bimrevision-agent 서비스에서 BIM 비교(bim-compare) 자식 프로세스가 V8 힙 한계(약 8 GB)에 도달하여 FATAL ERROR: Ineffective mark-compacts near heap limit 로 SIGABRT 종료되었다. 부모 BimRevisionService::run 이 이를 감지해 revision 작업(bim_id=17216, revision V5 vs V4)을 실패 처리했다. 오류는 단발성이지만 동시 시간대의 25개 클러스터를 포괄하는 서비스 저하 인시던트(2026-07-21-svc-cupixworks-any-bimrevision-agent--unknown-1)의 일부로 감지되었다.
