ChildProcessManager::setupEventHandlers | Child process stderr: FATAL ERROR: Ineffective mark-compac

What Happened#

2026-07-21 21:00:39 KST, cupixworks-any-bimrevision-agent production 인스턴스에서 BIM revision 비교 작업을 실행하던 자식 프로세스(BimCompareProcess)가 V8 heap 한계(8GB)에 도달해 FATAL ERROR: Ineffective mark-compacts near heap limit 로 종료되었다. 이후 부모 프로세스는 자식으로부터 SIGABRT 를 감지하고 bim_id=17216, bim_revision_id=25433 (V5 vs V4) 의 비교를 실패 상태로 마무리했다.
