What Happened#

cupixworks-any-bimrevision-agent production instance가 bim_id 17216 (IAD157 Coordination Model, V4 → V5) revision 을 처리하던 중, BimCompareProcess child process 가 heap 약 7.9 GB 에서 V8 FATAL ERROR: Ineffective mark-compacts near heap limit 로 SIGABRT 종료되었다. 부모 ChildProcessManager 는 stderr pipe 로 흘러들어온 V8 crash native stack trace 라인 각각을 logger.error(...) 로 기록하여 25개의 개별 error cluster 로 파편화되었다. 사용자 영향은 해당 revision 작업 1건 실패 (elapsed 883 s).
