Classified as: {OPEN} I actually hadn't thought to look for Postgres bugs, the system is so reliable for us, it just doesn't go wrong! I can trigger the fault be running a reload of the lfm database, and we've been running Postgres 10 & 13 for several years now without seeing this problem. Our symptoms match that bug description exactly, so I'm pretty confident this is the problem. I'll have to push through the right paperwork to get a Postgres update, and that will take a while Thank you so much for your time.
