Hi @heurteph-ei ,
thank you for your reply. Yes I’m seeing the exact same error message in the Matomo logfile. I could paste it, but since it’s identicalt I don’t think this would help.
The Matomo instance is only tracking 17 websites. We’re archiving all websites every hour. I checked resources for RAM issues, but there’s no bottleneck.
However I increased RAM limits for PHP to 4GB to make sure and I tried setting “–max-websites-to-process=5”. Unfortunately it didn’t help.
The affected website only has 2 million visits in 2024 so far. A much larger website with 14 million visits, is archived without any issues. The issue occurs only during processing the whole year (&date=2024-01-01). That’s why my gut tells me, that there is corrupt data breaking the archive process.
But I’m having no clue at all.
