I setup a new instance a week or two ago, and have some subscriptions to communities on lemmy.world. The logs for the Lemmy process are currently showing a constant flood of warnings for what look like ordinary activity (likes, creates, undos, etc). Here are two recent entries:

Tailing the Docker logs is like watching a torrent of these warnings, and I’m worried about the stress its adding to my fairly meager VM. Any tips on how to debug this? I’m proficient with Rust, so I’m willing and able to jump into the code if it’ll help.

    records can’t be duplicated in the database, the activity id is a unique key:

    lemmy=# \d sent_activity
                                                   Table "public.sent_activity"

      Yes, and if a duplicate does arrive (as appears to be happening), the current code doesn’t do anything about the corresponding database error, resulting in a scary multi-line warning for something that could be safely ignored. A new Lemmy administrator (like me) has no way of knowing this is at best an info-level event, or even just a debug-level event since it has no real effect on anything.
