After initially obtaining a low error rate, my i7-8700 (Ubuntu 18.04.1) started to receive a very high error rate. They were of the type:
"197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED" after reaching a time limit of 1 hour 25 minutes.

That machine was running VirtualBox 5.2.18.

But on another machine (i7-4790 running Ubuntu 16.04.5) the error rate remained low. That machine is running VirtualBox 5.1.38.

So on the i7-8700, I uninstalled VBox 5.2.18 and installed VBox 5.1.38. Now the error rate is low again, and the work units complete in about 2 minutes 25 seconds.

Therefore, it appears that most of the work units (though not all) are incompatible with VirtualBox 5.2.

Thanks for exploring this issue. We will investigate.

I still get a higher invalid rate on the i7-8700 (Ubuntu 18.04.1) than on the i7-4790 (Ubuntu 16.04.5), but it is much better now that I have changed to VirtualBox 5.1.38.
So there are probably still other problems, but the VBox one was the main thing for me. Good luck.

By the way, neither CPU is overclocked (a common source of errors), and both are running cool. I don't see errors normally.

Same errors (EXIT_TIME_LIMIT_EXCEEDED) with my Windows 10 and VirtualBox 6.0.4

I'll remove it and install 5.1.x version

I've gotten the "Postponed: VM job unmanageable, restarting later" error on probably 80% of my tasks. Am running VB 6.0.4; I see it's the most recent version, and I'm not one to backtrack or downgrade, so I'm going to keep it installed. Can anyone help out? Thanks... :)

Rolling back VirtualBox is the easy part. You need Linux too.
