Funny log entries (single numbers without context)

Hi there,

I recently upgraded to php8.1 as suggested by validate.php, so this is the current state:

Everything seems to work fine, though, but these entries are new, they never happened before. They also seem to repeat every time I reload the main dashboard. It’s exactly 50 lines like that every time, with exact the same order of numbers. I currently have 50 entries in the “Alerts” widget and I can’t imagine that this is a coincidence.

Any idea what’s causing this?
