This can only be checked/solved by a project admin. As a workaround you could request a fresh hostid from the server. You may try the following steps: 1. Detach from the project 2. Edit/create your cc_config.xml. Change the value for <ncpus>x</ncpus>. Use an x that is different from the current value. 3. Reload config files 4. Check the client messages to see if the changes have been accepted 5. Reattach to the project 6. Check the client messages to see if your host got a fresh hostid 7.-9. Same as 2.-4. but with the original x. ID: 35563 · Reply Quote

Can't say, since the project refuses to send any new tasks. I have installed cvmfs and Singularity on that host, I would like to try to help crunching ATLAS tasks. ID: 35580 · Reply Quote

The Computer ID displayed in BOINC client in the project's properties is 10453783. And it has a lot of successfully completed tasks as we see. Then something just went wrong...
