Server Version#: 1.21.3.4021 Player Version#: I am running as a docker container on OMV. The media drive is an external USB drive and worked up until recently. The automatic library updates stopped around the time I noticed that pictures weren’t being tagged. ---

I suppose you could experience this if the host OMV is monitoring too many folders > [@Linux Tips](https://forums.plex.tv/t/linux-tips/276247/9): > > Increase the number of directories Linux can monitor (inotify) for PMS The default size of the Linux inotify table is 8192 directories (\*1). When PMS is configured to update automatically when media is added, with properly organized media, especially music, this table rapidly fills and exceeds the default allocation requiring you to increase it. The solution to this is straight forward. Increasing the table size is easy. The first step is to determine how many directories to alloca… ---

Can you verify the max allowed watches? Not a docker expert… might be interesting if there’s a difference running this on the host vs. inside the container… ```auto sysctl fs.inotify.max_user_watches ``` ---

It’s the 8192 from the article you posted. I’ve even spun up a separate instance and only added my Music folder as a library, testing it still isn’t auto-updating. I have all the scan options selected in the Settings so I’m not sure what is going on here. ---
