Hi all. I need a help please.

I regularly lost access to the server during from one to three days. I mean that I can not to connect to the Web Gui, to dockers, to SMB and etc. It seams like server turn off, but I know that it works. I get access to server again after turn off server via disconnecting power cable from the socket and its further connection to the power supply.

I can't say exactly what started it, but a week or two before that I switched from plex to jellyfin and connected the graphics core to transcoding. And a month before that I connected a new disk to a separate pool for unimportant files.

See enclosed log please.

In my experience, these errors can be the result of the server being close to exhausting the memory, GUI can become extremely slow, like 1 minute to open the dashboard, try limiting the memory for VMs/docker services, or adding a little more RAM.

It could also be one or more containers hogging the CPU, try pinning only some cores to them, and leave cores 0/1 available for Unraid.

Also, recommend trying a couple of other things, go to Settings - Global share settings and set the Number of fuse File Descriptors to the max, and enable this:
