Randomly errors during backup

[sanchezdiegog]

Hi to all.
After upgrade from 6 to 7 PVE.
When trigger backup appears this error message "Backup of VM XXX failed - unable to open '/nas/dump/vzdump-qemu-XXX-2022_04_12-21_11_19.tmp/qemu-server.conf' at /usr/share/perl5/PVE/VZDump/QemuServer.pm line 210

Another error appears
Backup of VM XXX failed - unable to open file '/nas/dump/vzdump-qemu-XXX-2022_04_12-16_26_49.vma.dat' - Stale file handle

I change permissions to 777 and nothing, umoun -l nothing, restart fiscally the server...nothing.

Where a read something to guide me to solve this issue.
Thanks to all!.

Hello!
Same error here, proxmox host is fully upgraded, My mount folder is CIFS.
Any news/solution about this?
