Hi all! I see this when I try to get some new tasks of LHC@home: Пн 18 июн 2018 13:49:28 | LHC@home | Resetting project What's wrong? It seems to be this host: https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10453587 GPUGRID's tasks are being processed OK. |

That pc says its Last contact with the server here was 29 Mar 2017 Are you using the current URL? You may just have to go to the Boinc Manager and remove the LHC project and then go to the Tools/add project and use https://lhcathome.cern.ch/lhcathome/ |

You have Boinc 7.6.31. Please upgrade to 7.10.2. Sorry, its a Linux. Boinc 7.2.42 or your Version is useful. |

@ Rabinovitch Your host seems to be banned since Mar 2017. 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. |

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. |

Therefore you need to activate Test-Application in Preferences also as Atlas too? |

Believe me, everything is selected in my preferences (all applications of the project and also test applications). I have 2 hosts under same account. One is receiving and processing tasks, another get the error. |

Your active hosts are: https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10449491 https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10418662 hostid=10449491 This one is working fine. hostid=10418662 This one ran only SixTrack in the past, but SixTrack is currently out of work. VBox WUs will not run as the CPU doesn't provide VT-x. |

I said "seems to be". 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... |

https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10453783 Answer from the DB: "No such computer" Detach from the project to clean your local environment. Then Reattach. |

Yep, I have deleted all my anscient hosts from project's DB (there were all my PCs since 2007). Now the computer with ID 10550820 got it's bunch of tasks! |
