Hi,

I've got some issues after upgrading to 6.8.0. All docker containers and VMs hangs. The GUI are accessible but not the VM tab. 
I managed to save the log file and there's a red line with this (attaching the log file as well). Also attaching diagnostics file.

Can you confirm by rolling back to a previous release that these errors / hangs go away?

I upgraded to 6.8.1 and the problem is gone. For now anyway. 
I'll revert to an older release if the problem persist and see if that makes any difference. Thanks.

Spelling error

Thanks for the update!  Not sure what would have fixed this from 6.8.1, but either way, glad it's resolved for now!

Unfortunately i just had another crash. Cant access SSH, logs or anything. Think i'll try downgrade to 6.7.2 again.

Let us know if you are 100% stable on 6.7.2.

Same issues at 6.7.2 so i decided to get some new hardware. 6700k, ASUS Z170 PRO GAMING and 32GB 2666MHz RAM.
Installed 6.8.1 (recently upgraded to 6.8.2). Been running fine for a few weeks but just had another crash. This time completely froze. No picture when i connected a monitor. 

Is there a way to dump the logs to disk? I want to see what happen before a crash.
