find -maxdepth 3 couldn't reach immich's thumbs/<uuid>/XX/YY/file (4 levels deep), so it exhausted the 256x256 hash-bucket fan-out with no match and timed out on every run -- 3 spurious remounts/restarts of immich_server within 15 minutes of deploy, all falsely alerted as staleness. Drop -maxdepth entirely; -quit already stops at the first match via depth-first search, so it's fast regardless of tree depth.
