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

Le CRPD n’attend pas assez longtemps pour que l’opération de montage se termine. Le CRDI envoie un appel API (Application Programming Interface) pour fermer la session de montage alors que vProxy est toujours en train de monter des disques, ce qui provoque un conflit HTTP 409.

Ce problème a été signalé aux ingénieurs NetWorker.

Un correctif de code est attendu dans NetWorker 19.13.0.1 (27 août 2025 provisoire)

Ce problème a été observé dans un environnement où une machine virtuelle SQL contenait 10 disques (VMDK) et de nombreuses bases de données. Toutes les opérations de montage MSVMAPPAGENT ont échoué avec ce symptôme, alors que d’autres serveurs SQL plus petits se montaient sans problème.
