unRAID 6.7.2 becomes unresponsive and then crashes

[bluepr0]

Hello!

 

I've been running flawlessly unRAID 6.7.2 since it came out. However since a couple of days the server is hanging completely and I'm unable to bring it back unless I force restart.

 

Wake up this morning and it was looking like this

 

As you can see on the web interface, some of the cores are blocked at 100% (however that doesn't seem to be the case if you get into terminal > ssh > htop.

 

I was only running a VM, because this happened to me a few times already so I was trying to troubleshoot what's the problem. I'm also unable to stop or force shutdown the VM, I will get the message below

 

And this is what the VM itself shows in the video output

By the time I try to force shutdown the VM I'm not even able to get into the web interface, but I still get SSH access.

 

I have been reading the Help post here https://forums.unraid.net/topic/37579-need-help-read-me-first/ and followed the instructions, first I run diagnostics command to create the ZIP, however the powerdown command is not working. It won't shutdown 

 

In the logs > libvirt.txt I'm seeing the same message I attached before in the screenshot. However I'm not sure how to troubleshoot or what's really the culprit of these hangs.

 

Any help would be greatly appreciated so I can move forward and find a solution. Thanks!
