unraid freeze / crash

[Biau]

Hi all,

In the last month I started having issues with my unraid server.

My main usage is one VM running home assistant, then a lot of docker containers running plex and the arr suite (sonarr/radarr etc )

I only had freezes of the system with no more access and needed a hard reset (no screen attached).

 I've found some issues for people using macvlan so I switched to ipvlan and rolled back to 6.11.1.

I've disabled almost all runnings containers keeping only traefix/plexmediaserver/plex-auto-languages and addedd netdata for monitoring.

 

Yesterday at 6pm I started receiving netdata cloud alerts for docker_unhealthy_containers and then few more alerts for high system load.

 

System was stil somehow responsive using the web gui but when I tried to stop docker then everything goes wrong and i was not able to restart the box even from the console.
Here's the syslog file.syslog
Any idea of what happened ?
Why a container is able to crash whole system like this ?
At least how can I be sure which container is problematic here?

Thanks for your help !

Also btrfs is detecting data corruption, so run memtest and then scrub the pool.

Usually I'm using transmission and during this crash it was not running but it looks like it' not using libtorrent so I guess that's not my issue.
I've started a memtest let see what I've got.

After that just scrub or scrub + correct errors ?
Should I schedule it ?

ok it does not look good.
First time I have error messages in memtest I guess I should try each ram module separetely now.
