I'm not sure, but will get back to you tomorrow on the version.  The database
is postgres 9.6, with celery-something.  I'm sort of parachuting into this problem,
and only recently gained access to the airflow UI for it so I can do some digging
the next time it hangs.

Basically our dags are just glorified crontab wrappers around shell scripts.  What's
happening is that the dags stop launching (we know this because the shell scripts
leave timestamps on the logs they write to when they launch and exit), and bad things
start piling up with the rest of the cluster.

We don't have a lot of dags and they are very simple, but one of them runs every minute
and others run every 15 or every hour.
