Delete Duplicate Songs auto-restarts in an infinite loop after completion (v12.5 Docker remote)

[sean819]

Environment

• SongKong v12.5 Mirrored Docker (Premium)
• QNAP TS-873A, QuTS hero, Container Station
• Container command -r (remote mode), restart policy unless-stopped
• Volumes: .../music -> /music, .../songkongConf -> /songkong

Summary
After a Delete Duplicate Songs task completed, SongKong keeps auto-launching a NEW Delete Duplicate task every 1-2.5 minutes, each crashing immediately (no report produced) - an endless loop.

What happened

1. Ran Delete Duplicate Songs on /music/Unsorted (142,887 songs). Criteria “Sounds the same only”, action “Move duplicate to Duplicates folder”, Preview OFF.
2. Completed OK: DeleteDuplicatesReport02039, ~9h18m, ~35,245 duplicates moved.
3. Right after, SongKong began auto-relaunching Delete Duplicate every 1-2.5 min. Container log shows continuous >>>>/deleteduplicates.update_progress. check_progress shows a new “Started at” each time, near-zero progress, no report. Startup each time: songkong:remote dbinit -> songkong:remote started -> immediately Delete Duplicate.

Tried (all ineffective)

• WebUI Cancel -> a new one starts within ~2 min
• Restart container -> loop resumes (an active Monitor Watch Folder on /music/Unsorted also auto-resumed)
• Cancel Watch Folder -> continues
• Admin > Empty Database (“recreated successfully”) -> still recurs, now Selected Folder defaults to /music
• No scheduler in Preferences
• Inspected /songkong: Prefs/*.properties (general.properties has no startup key), Cache (metadata only), Logs - no obvious pending-task file
• Only effective fix: stop the container

Possibly related to SONGKONG-2974 (v12.5 remote not persisting task settings).

Question: In remote mode, what persists the “task to run/resume on startup”, and how can I safely clear it (which file or DB table under /songkong)?

Music data is intact - duplicates were only moved to /music/rebuild/duplicates, nothing deleted.

Okay, I will test this out myself tommorrow.

Delete Duplicates is not restarting for me in remote mode, but it seems like there is quite lot going on here, when restarting container no tasks should automatically start you would have to configure them in the gui.

You did run delete duplicates on a large folder, I wonder if there was some issue during the run that has contributed to this situation.

Can you run Admin:Create Support Files and did you make any modifications to the container?
