Looks like it may be an upstream issue in discord.py but I might just had to do some exception handling.

I may have a fix for this; it is in a separate branch while I test before I pull it into the mainline.

As an FYI, the LGBTea Cafe team is now also using the mentioned Dev branch. We'll let you know if we come across any issues 👍

Appreciate it. I have found that while it does help it does not fix the issue because that one location isn't the only one where Discord can throw an Exception at me, so I'll be updating that dev branch soon with more extensive exception handling to hopefully put a pin in this issue once and for all. Also I really love the name of your Team!

After almost a month of uptime the bot finally died again, so definitely the current version on the other branch is a great improvement.

I'm including the crash error below, in hops that that will provide some insight into the issue:

This is running on an Ubuntu 20.04.4 LTS bare metal server, using an AMD Ryzen 3 2200G.

Unhandled exception in internal background task 'find_messages'.

During handling of the above exception, another exception occurred:
