When I run the vacuums manually on a healthy system on 741, they take less than 30 seconds. I've stopped the cron vacuum and canceled all the outstanding vacuum processes, but the 803 is still struggling (1/2 hour later). I'll re-start the database, vacuum full analyze and restart the runs without the cron vacuum running.
