Books in processing queue not being processed

[heliostatic]

Currently running the main docker image and books added to the processing queue aren't being processed.

I'm not sure how to clear the queue, but I think that's the first step in debugging it.

Deleting the db and trying again did work, but still not sure why the processing was stopped before.
