Can you grab the [server logs](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) shortly after it errors out? That will help track it down.

OK - My head hurts … Had a look at the link (Thanks for that), the lead me to another that was talking about not being able to run the EAE stuff due to the /tmp FS having no exec set. Aha I said, cause I’m using a NAS /tmp is tmpfs which is in RAM and the mount is noexec so I remounted to see if that was the issue, still the same. Then I thought, the PMS is a container so maybe I can get it to use another directory is I tried setting TMPDIR as an environment variable for the container - no joy. Then I thought, lets map a volume /tmp directly into the container and again no joy. I also tried removing the EAE codec that one person suggested but the container recreates it when it starts so that didn’t work. either. So I don’t know if this is an issue cause it’s in a container or if it still would happen if I were running the straight synology PMS. ---

On Synology, you must handle the kernel table size FIRST. Docker is 100% dependent on host resources. When you get the EAE error, and you have a lot of directories, the notify table (which is how PMS knows you’ve added media) fills up. EAE requires two slots in that table. Therefore, if the table is full, EAE cannot run and will give the error. There is a procedure to address this for Synology. Give a read and ask with any questions. > [@Synology FAQ - Questions, Answers, and How-To's](https://forums.plex.tv/t/490215/22): > > 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… ---
