You think I should just reset lhc at home all of mine are still failing. I do have a squid cache, so maybe that's the source of my issues? |

Win11pro, all Atlas-Tasks running well, with Squid. https://lhcathome.cern.ch/lhcathome/results.php?hostid=10795955 |

You think I should just reset lhc at home all of mine are still failing. I do have a squid cache, so maybe that's the source of my issues? ATLAS EVNT files are very large and Squid does not cache them. The decision which file needs to be downloaded is made by the BOINC client based on the WU data it gets from the server. Hence, I don't think your Squid is the problem. Nonetheless, feel free to purge it's cache - it will rebuild automatically. A project reset looks more promising (no 100% guarantee). Finish all tasks in your work buffer before. |

A project reset looks more promising (no 100% guarantee).I tried two days ago a project reset first, but the returned task state kept 'in progress', so would have resent the 'lost' task after requesting work again. But after a project remove and adding LHC again, let get the task the abandoned state. |

Have Squid in a CentOS9-VM defined. So, it's no Problem to stop and start Squid. In this moment of start or stop, Boincmanager in Win11pro is waiting. |

I've lost 2 tasks (show as in progress in the LHC server but not physically on my system) due to this series of errors.

Did a project reset. See what happens. Otherwise it just keeps trying to download the same file that refuses to download because it's 'lost'. |

Did a project reset.greg_be: did the project reset solve your problem ? |

Did a project reset.greg_be: did the project reset solve your problem ? No. It sent the 'lost task' task again and that failed again. It just repeats it self. I don't know how to shake a 'lost task'. Any ideas? Clearing data out of BOINC folder for LHC? At this rate I will not get any new work until I can get rid of the lost task. |

I don't know how to shake a 'lost task'.Start reading before writing :) |

Start reading before writing :) Your smart writing is actually a repeat of what someone else wrote. So do you have a brain? I had no time this morning to scroll through everything and here I am 12 hrs later and about the only thing I see that MIGHT be of use is what Crystal wrote awhile back. Otherwise I don't see anything that applies to my simple set up in windows. Squid? I had no idea what they are talking about. |

Squid is a proxy and cach the Data at your PC. You can install a proxy or not. Atlas works now as before, after the problems last night at midnight. |

Squid is a proxy and cach the Data at your PC. Thank you about the information on Squid. I am downloading the massive file for the task. 7 minutes to download with DSL! That's a huge file! |

For me on one computer resetting the project does not fix the problems, I will monitor further. |
