I've rolled out our first 9.5 upgrade recently. Jobs were running fine till yesterday.
Backup jobs started failing randomly with the following error message.
Error: An unexpected network error occurred.
WINAPI: Cannot get file size. File: [\\FilSrv\FilSrv-CIFS2\FilSrv-CIFS2-jobs\soam1.vm-5192D2017-11-11T120158.vib]
The subsequent job succeeds. Any help in figuring out the issue / resolving it is highly appreciated.
