Hi! My server was doing it scheduled moving and backup operations and might be because it got overloaded, but mostly everything crashed:

• Unraid's GUI stopped responding and had to start (not restart!) ngnix through an SSH terminal.
• Docker in general crashed altogether. "Docker" page shows "Docker Service failed to start."
• Can't access shares through SMB on Windows machines, but shares are visible in the "Shares" page.

The task i was doing were a

• Restic backup using Backrest.
• Moving from cache to array.
• And probably the worst offender: Integrity plugin was hashing the newly moved files.

Maybe I'm asking too much at once from my poor 4670K?

 

Attached Diagnostics. I'd like to know what happened to prevent it from happening again. Thank you very much.

Try updating to 7.1, there are some changes that may help with these errors, they can make the GUI stop responding:

I see! Nice to know that there improvements towards a more stable UI. I'll be updating as soon as it's ready for production
