I am running the latest version of Plex for Synology NAS. 1.40.2.8395-7000
Recently, when I tried to scan my library for changes, I saw that Plex kept adding copy after copy after copy of the exact same album, to the point that my 215–220 albums, quickly turned into over 1600 and counting. It did not stop until I canceled the scan. By that point, I ended up with 5 to 10 copies of each album, all identical. When I would try to delete the extra albums, I would encounter an error message, saying something to the effect of the operation cannot be completed, or there was an error, something to that effect. Because of this, Plex has become unusable for me , At least for music. What is most frustrating, is that up until now I have had absolutely no problems with Plex scanning my albums correctly, but now all of a sudden, it has gone haywire and made it impossible to use it to play music.
I’m also having metadata problems with my TV shows, although in that case they are, I am seeing is manifesting in a different way. and again, as with my music, it’s a recent development, as both of these issues seem to have started roughly around the same time.
Any help trying to identify the Cause of this behavior would be greatly appreciated.
Wait three minutes (to fully start & log everything).
Pull & post the log files.
Scanning the snapshots is causing some other issues. It should resolve itself by not scanning the snapshot folders, but need to double check.
The Notify errors mean you’ve exceeded the number of directories Plex can monitor (you’re not really out of space). Not scanning the snapshot directories should bring you below the limit. If it does not, it is easy to fix things: FAQ 16: Increase the number of folders Plex can monitor

WOW. I never thought that snapshot creation would do this to my server. It seemed like a good idea at the time, but I have my media backed up, so it is not really needed… especially if it is causing these kinds of headaches.
I am going to disable them for my media folders and re-scan the libraries. See what happens.
Update: I actually took the semi-drastic step of deleting all the metadata as well as the snapshots associated with the media folders (just in case). After re-adding each library one by one, and re-scanning each in turn, the issue seems to have resolved itself.
