You can reduce your Number of CMS-Tasks in LHC-Prefs.
It seem you have 12 Threads and 12 Tasks running.
This is some overloading of your system.

What you can testing, Boinc have a upgrade only for Windows, from 7.16.11 to 7.16.20,
if this faulty Atlas are involved.
Have also upgrated Virtualbox to 6.1.30.
Saw also some faulty before in Win10pro and Win11pro.

This might be a temporary problem and so this job will be rescheduled for another time.

No Crystal,
have no RAM-Disk in use. Atlas is running with WCG-MCM tasks and Einstein-GPU tasks.
This crash of Atlas-Tasks was at 22 UTC.
Saw at 2 UTC ;-) some disconnects of the Network on this PC, and have no explanation.
One other PC (RYZENMP) had also this morning (after some sleep) two vm_image.vdi with yellow triangle.
Yes, it would be a good idea to use the best vboxwrapper for ALL Virtualbox- Tasks at Cern.

The Error was because of a yellow Triangle from a disruppted Atlas-Task.
After deleting this vm_image.vdi in Virtualbox App, other Atlas-Tasks started well.

What's about running Atlas or Theory instead of CMS, to see what happens.
They need also Virtualbox.

I'm running Win11 on an AMD processor. I believe Hyper-V is Intel specific and I never install anything but what is in the Boinc releases and all has worked fine for about a decade.

Hyper-V is a Virtualisation feature from Windows.
The stability of the Hardware is first thing of work.
Hoping you find the solution.

atm the flow of new tasks is ok.
There are Volunteers with problems in running a CMS-Task (for example short run less than 10 sec.)
This mean a lot of tasks from CMS have no restart for a normal using.

Ivan, we hoping you have a wingman for your input of new tasks in the near future.
Thank you for your work!

Do you have installed the extension pack for your Virtualbox-Version?
Do you have hyper-V active, this must be disabled?
