What happened?

Within the last few versions / during modest growth of my library, scheduled scans of the library have begun failing to complete. Clicking on the active tasks icon at the top of the page and canceling each task sometimes causes them to terminate, but this is not always true. Restarting the container (docker on Ubuntu 24.04 LTS managed with Portainer) also works. Upon restarting the container, a manually initiated library scan will complete, but the problem eventually returns.

In the logs, the "scan" items that are present look to complete, but I do see running scans in the UI as described.

This can happen with my modest Podcast library or my larger Audiobook library. My libraries are mounted NFS shares on the Ubuntu server.

I have about 4,300 items in my library, comprised of about 25,600 tracks.

The folder watcher is enabled for the library as well as hourly scans, so that could be a conflict. With that said, it has always been that way, even before the problem started.

What did you expect to happen?

Library scans eventually complete, even for larger libraries.

Steps to reproduce the issue

Start the container.
Configure hourly scans and watched folder for library/libraries.
Wait.

Audiobookshelf version

2.17.5
