Failed to create event: Permission denied @ rb_sysopen - /var/app/current/log/tesla_production-event

What Happened#

2026-04-23 15:02~15:55 UTC 사이에 cupixworks-worker 서비스(us-west-2)에서 Eventable::Events::Update.create_event 실행 시 Cupix::Event 싱글턴 로거가 /var/app/current/log/tesla_production-event.log 파일을 열지 못해 Permission denied @ rb_sysopen 에러가 반복 발생했다. 동일 호스트(ip-10-1-18-233)에서 배포 버전이 바뀌어도 지속적으로 발생했으며, 모두 Bim 모델(ID: 19207)의 processing_failed update 이벤트에서 트리거되었다.
