Over the last ~18h, our server is using close to 100% CPU.

Looking at Sidekiq, it’s busy running the same 5 jobs:

It’s always in “Just now” and they seem to be always re-running over those same 3 topic ids.

I tried restarting Discourse, but the situation remained.

Not sure if it’s related, but this started ~24h after we updated from 3.3.3 to 3.3.4. I don’t see any recent changes to `app/jobs/regular/sync_topic_user_bookmarked.rb` and I couldn’t spot any change on 3.3.4 that could be related, but I don’t know the codebase.

Any clue on what might be happening?
