Hey all, looking for some help here as i'm not quite sure what direction i should go. I'll jump into it.

I'm having constant issues with unstable VMs, Docker containers, and the Docker service itself. Today i noticed each CPU was also maxed out. I shut down my VMs and the docker service appears to have crashed.

I also noticed a CRC error on one of my drives from a few weeks ago, it has definitely been running fine since. I understand this can cause isssues, i'm bringing it down now (i think she's stuck) to re-seat the cables and replace if the error returns.

A number of months ago, i got a few new drives and an LSI HBA card, pre-flashed for jbod. I believe it had been running fine. The CRC error is on a drive ran by the HBA card. A little later, i installed the tailscale plugin (not docker). From that point, things have been really quirky. I uninstalled it, and yanked out some of the network config settings it had created (i think). The issue persists, but i also find it hard to believe my issues would be caused by the plugin.

I'm seeing a bunch of segfault errors in the logs, but they only seem to happen when running VMs. Using the SMB shares online doesn't seem to cause issue.

I'm including my logs if someone would be willing to take a look. I'm trying to look at this, and i have no idea where i'd even start. Some direction and maybe some resources to help me decipher logs would be greatly appreciated.

Thanks for your time.

spelling and more info

There are multiple apps segfaulting, and also btrfs is detecting some data corruption. My first recommendation would be to run Memtest.

Also make sure this has been taken care of:

If neither helps, one thing you can try is to boot the server in safe mode with all docker containers/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one, including the individual docker containers.

It was indeed the ram, thanks a ton.
