I'm seeing a ton of the following everytime Plex is transcoding. The directories in question contain .fuse-hidden files. Any ideas what's causing this?

Plex!  

 

For a much better and more useful answer, please post again in the support thread for the particular Plex you are running.

FWIW I've seen those messages too, but the directories in question do get deleted eventually. I wonder if it's a consequence of the "should I use /mnt/user/appdata or /mnt/cache/appdata" question?

Just in case anyone runs into this error, the solution is pretty simple.  In the official Plex docker there is a host path for the transcode folder.  I set mine to a location in mnt/user (on the cache drive) and also tried pointing it directly to the same folder using /mnt/cache but still got these errors.  Setting the host path for transcode to /tmp (which is in RAM) resolved this issue.

 

I have direct IO enabled, so it's possible that's causing an issue as well.
