Right, I forgot to paste the actual entry 
{
"reqId": "Qb9kGneg5CEViJqBGCQq",
"level": 2,
"time": "2025-10-29T09:09:57+00:00",
"remoteAddr": "",
"user": "--",
"app": "files",
"method": "",
"url": "/nextcloud/cron.php",
"message": "User erik still has unscanned files after running background scan, background scan might be stopped prematurely",
"userAgent": "--",
"version": "32.0.1.2",
"data": {
"app": "files"
},
"id": "6901fa0e341e2"
}
And the solution seems to involve a database query: User x still has unscanned files after running background scan, background scan might be stopped prematurely - #4 by simonspa.
Not really, I just saw errors in the log, and thought it’s a good idea to fix them.
