Playlist suddenly overfilled with 9992 unwanted songs from library - Plex Client bug?

Server Version#1.43.2.10687

Plex Player for Linux :1.112.0.359-0d79a49f
Player Version#: v4.12.4 Plexamp

Hi @ll,

I just noticed that one of my Playlists suddenly has maybe my whole music collection inside one playlist. The playtime now takes 31 days. :smiley:

It’s impossible that this could have been mistakenly done by me, because I don’t believe that there is a “add all media to this playlist button”.

I only remember, the last interaction was adding a new song to this playlist but that one song has not been added, but instead all other media. Like the interaction has been negated.

Whats the easiest way to get rid of these songs again? Or do I need to copy and paste every single song to a new list and delete this one?

The only way to revert such an action, would be to restore one of the database backups: https://support.plex.tv/articles/202485658-restore-a-database-backed-up-via-scheduled-tasks/

You should try and repair the restored database file, just to make sure that it doesn’t already contain corruption, which could eventually grow and cause issues like the above. https://github.com/ChuckPa/DBRepair

Well, kinda hard to find a good and sustainable solution.

I am not restoring the database, because I have added my wife with a new account and she altered some playlists, maybe this would have reverted some things she might have added.

That’s why I just created a new playlist and added the songs from the old one to delete it afterwards.

I yesterday ran the DB-Repair script and noticed this Indexing issues:

Checking FTS (Full-Text Search) indexes
FTS index ‘fts4_metadata_titles’ - DAMAGED
Error: Error: stepping, database disk image is malformed (11)
FTS index ‘fts4_metadata_titles_icu’ - OK

Use ‘reindex’ command (option 6) or ‘automatic’ (option 2) to rebuild.

I made the automatic repair and checked everything again. All was good so far.

Today I added some more songs to my new playlist and split spider-noir into 2 show’s and checked the Database again.

I again had the same issues.

Why does this happen so quickly? Why is the database so sensitive to changes and requires regular repairs? That’s no problem for administrators, but as a consumer this is kinda disappointing having to continously maintain the DB after a few changes.

Is the plex data folder stored on a local volume?
It is not in any way accessed over a network file protocol?
There is no watchdog active which is automatically stopping and restarting the server when it is for some time fully “busy” and thus, slow to respond?

Things like this are like a guaranteed way to damage the database.

data folder is stored on my array on the same host running the container

What is not accessed over network? The data folder or the media server? I don’t access the data folder. I rarely move files, but I do that on the same host via ssh.
I don’t have any automatic watchdogs, scripts or other things that might interact with PMS. I just use things like tautulli on the same host, but this just tracks the statistics.

I never experienced any performance issues with plex, since we are just 2 1/2 people without constant usage of plex.

The server accessing its data folder.

Nope, no network connection. Just a bunch of hdd’s that automatically spin down after 15 minutes.
