NVP-vProxy: Mounten der SQL-VM-Wiederherstellung schlägt fehl "HTTP 409 (Konflikt)"

Die SQL-VM-Wiederherstellung wird über den Data Protection Restore Client (DPRC) durchgeführt. 
Der Mount-Vorgang schlägt fehl und meldet HTTP 409 (Konflikt):

Die flr-server.log des NetWorker-Servers meldet denselben HTTP-Fehler:

YYYY-MM-DD HH:mm:SS [https-jsse-nio-9090-exec-5] ERROR c.e.f.s.i.FsObjectServiceImpl.createVProxyBrowse 812 - Browse backup sessions were not created correctly - possibly a bad mount for sessionid: FLR-SESSION-ID

Der DPRC wartet nicht lange genug, bis der Mount-Vorgang abgeschlossen ist. Der DPRC sendet einen API-Aufruf (Application Programming Interface), um die Mount-Sitzung zu schließen, während vProxy noch Festplatten mountet, was zu einem HTTP 409-Konflikt führt.

Dieses Problem wurde gegenüber dem NetWorker-Engineering gemeldet.

Eine Codekorrektur wird in NetWorker 19.13.0.1 erwartet (voraussichtlich 27. August 2025)

Dieses Problem wurde in einer Umgebung beobachtet, in der eine SQL-VM 10 Festplatten (VMDK) und viele Datenbanken enthielt. Alle MSVMAPPAGENT-Mount-Vorgänge schlugen mit diesem Symptom fehl, während andere kleinere SQL Server ohne Probleme gemountet wurden.
