LHC@home

I'm running on a Mac Mini (macOS Big Sur 11.5.2) and recently had to rebuild my system disk and the disk where my home directory is located from a Time Machine backup. I also re-installed BOINC (v7.16.19), VirtualBox (6..1.26) and its corresponding Oracle VM VirtualBox Extension Pack. I'm not running a local proxy HTTP server.

My CMS tasks are all failing with 'Error while computing'.

My VMS console showed this (for a single task):
https://www.dropbox.com/s/0a791879nscyjo4/VMS%20console%202021-08-25%20at%2006.15.04.jpg?dl=0
The VMS log for the time of this failure is:

My computer is listed twice in my LHC@home 'computers on this account' page. Should I merge these entries?

Could be a corrupt CMS vdi or a corrupt LHC BOINC account file.
You may try a project reset first.


1. Set LHC@home to "no new tasks".
2. Cancel and report all tasks currently in your work buffer.
3. Backup your app_config.xml (if there is one).
4. Reset the project.
5. Restart BOINC (just to be sure)
6. Restore your app_config.xml (if there is one)
7. Request fresh work
8. Reload config files (only if you use an app_config.xml)
9. Check how the first task behaves.


If the error persists try to detach from/reattach to the project instead of a reset.

...Should I merge these entries?

Computers can only be merged if at least one entry doesn't show any task records.

Looks like few other users have similar problems.
So, this could also be a temporary problem caused by a CERN backend system.

Thanks, I'll try these steps if it turns out not to be a server problem.

Since CMS came back after Monday's update, I haven't noticed any problem with them (knock on wood).
