I have been observing a weird issue for a while.
After a random amount of time my server enters a sort-of soft crash. 
The Web GUI, the Terminal and the VMs crash.
The Docker Containers continue running without an issue. Since there is no way to obtain logs from the server because of neither ssh nor web gui working anymore. I set up a syslog server and have attached my complete log since the last reboot. Server is running 7.0.0 but this issue has been happening on v6 before.

Unfortunately, there's nothing relevant logged, this can also be a hardware issue, 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.

I have an update. It is most likely a hardware Problem. It crashed again. This time however i did not power cycle the system and just pressed the reset button.
After unraid had booted up again one of the SSD's was not showing up anymore. It did show up again after i restarted the server. I am not sure whether it is a problem with the SSD or with the Mainboard/CPU. Do you have any tips to diagnose this further?

Extended smart test compeleted without errors. Smart report of said M.2 is attached.

Try this, it can sometimes help with dropping NVMe devices, on the main GUI page click on the flash drive, scroll down to "Syslinux Configuration", make sure it's set to "menu view" (top right) and add this to your default boot option, after "append initrd=/bzroot"

nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off

e.g.:

append initrd=/bzroot nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off

Reboot and see if it makes a difference.

Thanks. Will do and provide an update in the future. What exactly does it do?

It disables some power saving features that can sometimes cause the device to drop.

I have not had any crashes since, so i think the issue is solved. Thank you again for your help
