@thomas Actually, I'm not really sure, I did three things. First, to confirm the trends weren't right, I opened the Rails console and manually executed TrendingTags.update!

I immediately noticed the trends became different, which suggested the scheduler wasn't doing its job.

I found no obvious issues in the Sidekiq web UI, but I suspected it might have been some hiccup with unique job locks, so I actually removed all locks from Redis through the console and then restarted Sidekiq
