Hi, I recently set up a new host and was experimenting with different OSes, which led to a few failed tasks on LHC@home. Some of it was due to OS-specific issues, and some was probably just me forgetting a step during setup. I wanted to check, does failing a handful of tasks like this actually cause any problems for the project? I noticed there's a limit of 3 failures per job. What happens after that? Are they recycled and sent out to other hosts, or are they discarded? Also, I currently have a Theory job that's been running for over 5 days. Based on its current speed, it looks like it would need around 50 days total to finish. Should I abort it? Here are the container logs for the LHC job (from container): https://paste.opensuse.org/pastes/a8556015cc51 To be clear/honest, I used a local Gemma to clean up the grammar and style. here. |

In reply to HumbleIdealism's message of 24 Apr 2026: I wanted to check, does failing a handful of tasks like this actually cause any problems for the project?Short answer, no. Depending on the project's settings, many projects will use two or more results and compare them to determine if they are Valid or not (Tasks with _0 on the end are the original Task, _1 the first copy, _2 the second, _03 the third, etc). Where a result is an outright error (faulty system, programme, data file, network issue, aborted by the user etc), or the system misses the deadline, another copy of that Task will be sent to another system. If a project doesn't compare Tasks for Validation, then a _1 Task is the first resend of a Task that errored out. If they use two Tasks to compare for Validation, then a _2 Task is the first resend of a Task that errored out. If a project compares 3 Tasks for Validation, then a _3 Task is the first resend of the Task that errored out). Once again, depending on the projects settings, a Task may be declared faulty if more than two return errors, or it may be more than 10 are returned as errors before the Task is declared faulty (or anything in-between).
