Note: I am not certain if this is a bug in Discourse. I have tried to collect necessary evidence, and so far I have not found anything pointing to our infra/setup. Our configuration is as vanilla as as possible at Tappara.co Observed phenomenom: Chat-like rapid discussion topics stop updating auto…

Well, it’s not a bug but a feature :sweat_smile:. When your web workers start to be overwhelmed by requests, we introduce delays in the persistent connection that auto updates the topic when new posts arrive. If you are seeing this and low CPU usage as reported, please increase the number of unico…

We are already at 11 Unicorns, on a 6-core VPS. Like said, this never occurred during the previous season, latest in March. Occurs now even with moderate traffic. Also this happens a lot more on a mobile device, especially Android Chrome, than it does on a desktop. Also, we have been able to exhaus…

I am working on analysis of this issue over the next 2 weeks, it will take time to improve

Great! Could you confirm whether there has been been a recent (6 months) change or regression, that has caused this? In the mean time, I think I’ll pump up the unicorns for tonights game and see what happens. If we can support in any way, just let me know.

@falco The number of unicorns is definitely not the key. I increased them to 15 for toninghts game. The game topic was calm, only 700 messages, but constant freezing was observed. CPU load was mild, in between 5-25%. The more I investigate this, more likely it seems like an issue and regression, bu…

I think there is a bug in the client where it basically stops updating after it gets 1 error. My suspicion is that you are experiencing this cause your users are getting rate limited. Will be investigating making the client more robust this week, as I said earlier, this is fiddly code and will take…

Great. In the mean time, I’ll test if disabling the global limiter would be a workaround. We’ll know on wednesday.

Debugging this issue lead me into thinking the UX of a near real-time discussion in general. Many communities deal with real life events, which naturally “push” the discussion towards a chat-like rapid conversation. It can be the stock market, a major product launch event, or a game (eSport or physi…

I like that idea, but it would need some kind of reverse shadow banning so people will always see their own posts immediately. If they don’t then they might be double or even triple posting, thinking that the forum does not work.

I just merged this: [imagem] PERF: backoff background requests when overloaded (#10888) discourse approved commit PERF: backoff background requests w…
