Plex recently added content error on library scan

Plex Media Server
1

Hello,

I have a hard to tackle issue with my Plex server. I have Tautulli set up to listen to Plex newly added content and to make a notification about the said content.
The issue is that every time a library is scanned, a notification for a specific content (Marvel’s Agent of Shield in my case) is sent. Regardless of if there is any new content on the server.

I have posted this issue on the Tautulli subreddit for help. (link: https://www.reddit.com/r/Tautulli/comments/i19691/recently_added_notification_spamming_for_no_reason/). A developer there, told me the problem was on the Plex side of things and offered some help. With no success.

Here a few information about the situation

  • Server Version#: 1.20.0.3125 (latest)
  • The server runs on a Debian 10 VM. This VM runs exclusively Plex.
  • Tautulli runs on a Debian 10 LXC, this container runs exclusively Tautulli.
  • Both of these host can contact each other.
  • I have set to scan all my libraries every 30 mins, thus generating a notification every 30 minutes.
  • When there is some new content, that does not prevent the right notification to be sent, it means the parasite notification will also be sent.
  • My Plex server is a fresh install from 10 days ago. (Had to migrate from FreeNAS to new server running on Linux)

What I have already done with no success:

  • The Plex Dance TM
  • Check for database corruption and repair it

So please, help, this is a real issue for me, as I use these notification to notify my user base for new content.

Is there a way I can reset all the recently added content db or cache in some ways ?

Can someone at least tell me what is in this DB precisely so I can whether I want to delete it completely or not ?

Why are you scanning your entire library ever 30 minutes? You should only need “Run a partial scan when changes are detected” along with Update my library automatically.

While this is not the cause of my problem, because even with the automatic scanning, the server triggers an event for the wrong content alongside the correct content.

I’m scanning every 30 minutes for two reasons:

  1. In my experience the automatic scanning when changes are detected slowly
  2. I’m eager to have the new content as soon as possible

To get Plex’s attention you will need some logs.

Complicating the issue is Plex running in a VM, how is the media presented to Plex? Through NFS or SMB shares? What is the host OS running? Where is Plex’s data directory located?

The error occured on 05.08.2020 around 07:56:10 If anyone wants for have a look. I found nothing relevant other than the server thinking this file is new (which it’s not)
/media/series/Marvel's.Agents.of.S.H.I.E.L.D/Season.03/Marvel's.Agents.of.S.H.I.E.L.D.S03E22.Ascension.(2).mkv

The VM is a Debian 10, as mentionned, it accesses the files over NFS. The host is Proxmox. And Plex’s data is in the default path when installed on Debian 10.
/var/lib/plexmediaserver/Library/Application Support/Plex Media Server
