Describe the issue

With a fresh install, when trying to do an initial scan of the library, the docker container will crash. The docker logs indicate that it is running out of memory. It tried adding the following to my compose file, but it still crashed after consuming about 9G of RAM as shown in Portainer.

    deploy:
      resources:
        limits:
          memory: 16G

Here is the docker log from when I started a scan to when the container crashed:

Are there any ebook files in the library (PDF, CBZ, CBR, epub)?

I have 7 books with supplemental PDF files in the same folder as the .m4b and 134 .m4b files total in the library

Are you using a network file system? Can you try creating a library with just a few m4b files to test that you can scan in books?

The books are stored on an NFS share. I tried just 5 books, one of which did have a supplemental PDF, with the same result. I just deleted the supplemental PDF, and re-ran the scan with the same result.

You can't scan in a library with a single audio file? Can you share your docker compose?

Sorry, I just started a scan with just one m4b file in the library, but it did the same thing. Here is my compose file:

Welp... I'm an idiot, and sorry for wasting your time... I somehow accidentally mapped the root ( / ) as the audiobook library, instead of /audiobooks.
