DPRC는 마운트 작업이 완료될 때까지 충분히 오래 기다리지 않습니다. DPRC는 API(Application Programming Interface) 호출을 전송하여 vProxy가 디스크를 마운트하는 동안 마운트 세션을 닫아 HTTP 409 충돌을 일으킵니다.

이 문제는 NetWorker 엔지니어링 팀에 제기되었습니다.

NetWorker 19.13.0.1에서 코드 수정 예정(잠정, 2025년 8월 27일)

이 문제는 하나의 SQL VM에 10개의 디스크(VMDK)와 여러 데이터베이스가 포함된 환경에서 발견되었습니다. 이 증상으로 인해 모든 MSVMAPPAGENT 마운트 작업이 실패했지만, 다른 소규모 SQL Server는 문제 없이 마운트되었습니다.
