PMS shuts down (crashes) about the same time every week... Logs included

I’m assuming you’re on the public release at the moment?

There is a fix in the 1.43.0 beta version which is most likely the issue you’re seeing.

You could install the beta and see if that solves your issue, otherwise try to remove the problem album from your server for now and wait for the beta to release to public (in the new year).
