Hello, Yesterday I try steam-headless, steamos, kasm workspaces and kodbox containers on my unraid. I leave only steamos container for testing and remove rest. I stop steamos container for the night. Today morning I  noticed in Fixcommon Problems plugin that system is out of memory. I noticed also warnings that docker image utilization grow to 70%. I remove also steamos container and all that not used containers  from appdata directory. I also set: `docker system prune --all --volumes` command. Now my docker utilization in 48%. 
I attach diagnostics for someone who can help me figure what happen.
Regards.

If it's a one time thing you can ignore, if it keeps happening try limiting more the RAM for VMs and/or docker containers, the problem is usually not just about not enough RAM but more about fragmented RAM, alternatively a small swap file on disk might help, you can use the swapfile plugin:

Thanks @JorgeB. I have 64GB RAM so I was sure that is enough. I will try with that swap file plugin but I see it's for BTRFS formatted drives. I have now every drive in xfs.

Regards.

What makes you think that?   It works fine with xfs formatted drives.

Hi, I read that:

At one point btrfs drives did not work correctly.   If you look through the change history, then you will see that adding support for btrfs drives was one of the improvements and that is what that text refers to rather than meaning only btrfs drives.

OK, no problem. I install this plugin and it work. Can You tell me what options set will be best for me? How large set that swap file and swappiness?
