Leftover files in SAB TV category folder

Sonarr version (exact version): 2.0.0.4472
OS: Windows 10 x64
Debug logs:
Description of issue: Sometimes, I get leftover files on SAB’s TV category folder path. An example is this:

E:\raw\TV_UNPACK_Elementary.S05E11.720p.AMZN.WEBRip.DD5.1.x264-DRACULA\Elementary.S05E11.720p.AMZN.WEBRip.DD5.1.x264-DRACULA.mkv

I then got the History of that particular release and have this:

The current file that I have in my Sonarr TV series folder for Elementary is this:

E:\TV\Elementary\Season 05\Elementary - S05E11 - Be My Guest - [WEBDL-1080p - DRACULA].mkv

From the History itself, here’s my deduction:

1.) Sonarr sends the 720p webdl (or webrip, are these one and the same?) release and sends it to SAB.
2.) SAB completes the download, Sonarr process the file and transfers it to the Elementary folder BUT did not delete it from the SAB TV category folder.
3.) Sonarr detects an updated 1080p webdl release and sends it to SAB.
4.) SAB completes the download, Sonarr process the file, deletes the 720p release that is already on the Elementary folder, and transfers the 1080p release to the Elementary folder (successfully deleting it from the SAB TV category folder).

The problem lies in step number 2. Why is this?

Sonarr moves the file, so there should be no video file left behind unless there was a duplicate.

If the folder is left behind check the logs for Sonarr failing to delete the folder, if it says it deleted it and there isn’t an error then to Sonarr it was successful.

When would there be an instance of a duplicate? Sonarr is the one sending those downloads to SAB so it sgould know if there’s a duplicate or not.

Can this be seen in the normal non-debug logs?

I’ve seen cases where SAB was extracting the files twice so there would be two files in there and one was left behind. In fact you had this exact issue once before: Leftover files not being deleted

Sonarr will log that it’s deleting the folder at the end at debug (so debug logging would need to be enabled) to see that, but it it won’t delete it for some reason it should log a warning and if it failed to delete it should log an error.

You’re right! Sorry, I missed my own thread there. Thanks for pointing that out.

The only thing I see in the info logs related to the leftover movie file is this:

Any clues?

No clues there, those are from the grab only.

Does that mean I have to turn on trace logging again and wait for this issue to happen for us to have a better idea?

Yes, otherwise we’re completely blind.
