Alright, summary for the forum peeps:
- Very likely some data inconsistency in your database that existed for quite long and just now surfaced.
- It’s nothing problematic, only some file cache entries that point into the woods.
- You can find them in your database via:
SELECT DISTINCT * FROM oc_filecache AS f INNER JOIN oc_mounts AS m ON m.storage_id = f.storage WHERE size < 0 AND parent > 1;
- You can remove the relevant entries by their
fileid
listed in the first column of your results:DELETE FROM oc_filecache WHERE fileid = <your id>
- MAKE SURE TO BACKUP YOUR DATABASE BEFORE (or at least this table!)
