Sounds like you hit the max directory threshold.

The easy verification of this:

1. With DEBUG [server logging](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) enabled,
2. Restart PMS
3. Wait 3 minutes (no activity)
4. Download the logs ZIP file
5. Open it and look at “Plex Media Server.log”
6. Search for “No space left on device” as it attempts to setup the inotify service

If you don’t find anything, please share your logs ZIP file and we’ll look.

Otherwise –

What’s happening here -

1. Linux has a table in the kernel for the file notification service (inode notify - inotify)
2. When that table fills, New content additions won’t notify PMS to scan and add the new media files

The solution is simple – Increase the size of the table from its default to accommodate what you need (with a bit extra for growth)

On Synology, we have to increase the table size indirectly.

Here’s the How-To which will let you figure out what you need, round up to add room for growth, then update the kernel table.

> FAQ 16: Increase the number of folders Plex can monitor Applicable to all supported versions of DSM. When the Linux ‘inotify’ table fills up, this will cause when Plex to stop automatically detecting new media you add to the server. It will also manifest when there are transcoder problems with Dolby audio codecs. Linux has a default table size which is static. We can increase this at will. On some versions it’s 8192. On newer kernels, the default is 65536 folders. This is easy to incr…

You do this to DSM itself. PMS in the container uses that same table.
