Probably wrong disk allocation / min free space on the isos share which it gets downloaded to. Post diagnostics.

There is no time limit. Post the error/log you get. What's "Vostro"?

Look at syslog/post diagnostics, there likely is something else that's wrong.

Flash backup is not handled by the plugin itself, it just calls Unraid's "generate backup" function and that makes a zip.

Unrelated to the plugin, unraid issue https://product.unraid.net/p/7-3-2-dashboard-nginx-log-spam-from-stale-docker-template-fallback-icons

Yup, that would be correct for a regular home PC which would have some swap space and would misuse an SDD/HDD to put stuff on that should be in RAM, but Unraid doesn't do swap. When there's no RAM for the essentials something needs to get killed.

Run fewer containers = make it slow, how? 8GB is just not enough to run a stack of apps like you seem to have.

Post diagnostics, maybe it's possible to mount the drive read-only. Set up proper backups and regularly check they don't break.

Had you set a custom path? Because at least if you select a share from the dropdown it works fine, had it running like that for years.

Ran a memtest before commissioning the new hardware?

No, Windows only supports connecting to a given server with a single set of creds.

But that's what you say you have?

When it fails it'll tell you why in the output, look at it... They are orphaned images, not containers, i.e. images that have been downloaded but are not currently being used by any container. That only cares about the appdata folders, not containers or images.

Because you entered something wrong and the container fails to build. Can just hit back and correct, or go to apps->previous apps, select reinstall and correct before applying.

Memory is only used if there's nothing else needing it.
