Python using 75% CPU time
Cheers I think that clears it up :)
atlas error
Your computer reports 3.79 GB RAM:
https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10846970
This is enough to run XTrack.
ATLAS/CMS/Theory recommend at least 16 GB although they may run with at least 8 GB.

Ubuntu 20.04 support?
This is the recommended CVMFS starting point:
https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5594
This option shouldn't be used (remove it, except if you know exactly why you need it):
CVMFS_CLIENT_PROFILE=single
This is recommended (as a private volunteer you should understand it as a MUST):
CVMFS_HTTP_PROXY="auto;DIRECT"
CVMFS_USE_CDN=yes
As for CVMFS_USE_CDN/Cloudflare/openhtc.io
https://openhtc.io/
openhtc.io is hosted by Cloudflare.
You don't need a Cloudflare account to use it.
openhtc.io distributes CVMFS/Frontier content required by ATLAS/CMS/Theory via a worldwide proxy network (hundreds of Squid proxies).
If you don't use the CDN CVMFS/Frontier get their data via "stratum-one-servers" (only few worldwide).
Getting the data from a CDN proxy close to your location instead of getting it from a stratum-one located far away is usually faster.

Thanks all! I thought we have local problems and not picking up jobs ... they are coming now.
Grafana job graphs are borked
The graphs are looking normal again. Thank you!
Why is there no ALICE application/work?
LHCb didn't send any BOINC work since end of 2018.
See here:
https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=4886&postid=37382
The post may include a hint why there is no ALICE BOINC app.

atlas error "error while computing"
I wonder why it took nearly 1 day and >70 failed tasks to notice something is wrong.
What about the TRIUMF-LCG2?
They run about 90 atlas clients but no valid results for weeks.
New ATLAS vbox64 version 3.03
Yes.
Guide to Getting Quickly Started Running Native ATLAS (Ubuntu 20.04 on WSL2)
I do belive even though they are on differant os you still need to set boinc up like you would for multiple clients on the same os. Different dir, ports. Add the cfg for multi boinc in the main direction etc. I had the same problem
Fails to create VM?
I'll be sure to so that next time.
The 1 thing that changed that could've caused this was running windows update for patch tuesday. However, I suspended all non-running tasks and let the running ones finish. Maybe something didn't close properly.

New ATLAS tasks always fail
You're right. Seems like the automatic update for cvmfs was causing some issues this morning.
no VM console button for ATLAS in Windows 11
Hence, the conclusion seems to be: On Windows 11, the console button does not work with ATLAS tasks. still I would be interested in knowing whether all other Windows11 users make the same experience, or whether there is something that can be done in order to make the VM console show up and work.
Yes, I see the same on my Win 11 machine (Boinc 8.0.2). So I am using the VirtualBox Manager to bring up the console.
Did you installed the corresponding VirtualBox Extension Pack?
Yes I did.

Atlas tasks have started to fail.
Yep, all invalids seem to have this error:
