ChildProcessManager::setupEventHandlers | Child process stderr: 10: 0x10c69a6 v8::internal::Factory:

What Happened#

2026-07-21 21:00:39 KST, cupixworks-any-bimrevision-agent(clark-vdc, us-west-2)에서 BimCompareProcess child process 가 v8 heap OOM 으로 SIGABRT 종료했다. bim_id 17216, src_revision 25433(V5) vs prev_revision 21647(V4) 비교 작업 중 154,331 created + 57,346 deleted = 211,677 개 element 를 로드한 뒤, forge-agents 의 ForgeAgent.extract 호출이 8GB 힙 한도를 넘어서서 "Ineffective mark-compacts near heap limit — Allocation failed" 로 종료했다. 이 25-cluster 이벤트는 동일 job 하나에서 발생한 stack trace/GC 로그의 각 라인이 서로 다른 fingerprint 로 클러스터링된 결과이며, 실제 impact 는 단일 BIM revision job 1건이다.
