First, I restarted mailman3 and the error at http://mailman3.jab.org:8000/persisted. Then I killed and restarted postorius and the error cleared up. The postorius instance is accessible again.

Postorius output showed (I don't see a postorius output log file anywhere so I don't know if I can pull up history farther back?):

And the mailman3 var/log/mailman.log looked like this throughout:

That's me stopping mailman on Jul 06 18:08. Nothing in the mailman3 log showing any errors anywhere.

Please let me know if there is other data I can pull out for you.

Thanks
