Hello,

It happened a few times and I did not think much of it and just restarted the server (very uncleanly because the "normal" shutdown wouldn't work), but I think my server has a deeper issue:

The server seems in a limbo states randomly where everything seems to works and not work at the same time. Most dockers seems responsive when I reach their web UI, others are not. The Docker tab in Unraid UI says "Docker Service failed to start." but in a weird way.

Unraid UI is not updating the dashboard, but I can navigate the menus fine.

Here is my diagnostics attached that I could download from that exact state.

Would anyone knows why? Is it a memory issue?

Thank you!

Flash drive issues, try a different USB port, if the same, replace it.

Thanks @JorgeB ! You are always so quick to answer!

I will do that.

EDIT: Probably will confirm, but this is the CLI output from me restarting Unraid.
