What Happened#

2026-07-21 21:00 KST, cupixworks-any-bimrevision-agent 서비스에서 BIM 리비전 비교 작업(bim_id=17216, V4 → V5)을 수행하던 child process가 V8 heap 한도(~8 GB) 를 초과하여 FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory 로 abort 되었다. 21:01 KST 에 부모 프로세스가 SIGABRT 로 child 종료를 감지하고 BimRevisionService::run 이 예외를 전파했다. 동일 태스크에서 25개 cluster 로 fingerprint 가 분리되었지만 실제 사용자 영향은 리비전 한 건 실패이다.
