Hey @agemo

Could you please check for me this site setting on your instance?

This is a default setting for users. Users can override it in their profile:

user setting1312×984 85.6 KB

What I think might happen:

  1. You have always or only when away default setting;
  2. Topic was created in watched category. System wanted to notify all/only away users;
  3. Bunch of Sidekiq jobs were lodged which were crashing because of rate limits;
  4. Default watched category was removed, but this is not removing already enqueued Sidekiq jobs;
  5. Sidekiq retires failed jobs;
  6. When the post was moved to a new topic, previously wrongly created notifications were deleted;
  7. When notifications were deleted, retrying jobs were completed successfully without sending emails.
