I'm on Ubuntu 16.04 Xenial using the latest 3.2.0.1 and when I run it, at some point the entire program dies leaving this stacktrace:

I assume this is a temporary 503 on behalf of Flickr, but is there a way to build in retry logic so I don't lose my whole (~20GiB) sync?

This is a good feature but it is not planned for development at this point - you (or someone else) are welcome to create a PR that incorporates this
