Hoi,

1) Does anyone have the same problem: of the 100 LCH tasks I run,
67 resulted in a fault?
Is this a local problem or a general problem?

2) The LCH tasks (that uses 20 CPU's) are @ 100%, but after 1d 5h,
they are still running? The status of 100% was reached after 22h??

Thanks for the help.

Greetings,
Ronny

[I moved your question here as it's the more appropriate place for such questions]

Hi Ronny,
Even your valid tasks are finishing very early with a "session locked" error.

Check in VBox if the number of VMs is the same as the number of tasks you have running. It could be that you have 1 or more "ghost" images in VBox that are interfering with other VMs starting up properly. These can sometimes be left over if Boinc doesn't tidy up properly on exit. Delete/Release any extra ones. Exit Boinc and allow running VMs to save. Look in File/Virtual Media Manager for any .vdi images that have a yellow triangle. Delete any you find then restart Boinc.

Hope that helps.

All my LHCb tasks fail on my main Linux box. Native Atlas@home tasks run perfectly on my Linux laptop with the same OS, SuSE Linux 42.2 and VBox 5.1.18.
