I had to push the value up to 240 to make the errors stop totally. I haven't noticed any meaningful difference in my World feed after doing this, but my error log's much cleaner now.

I'm still not seeing movement on the Lemmy side of things. I went to check the Lemmy forums I'm subscribed to here, to see if there's a similar issue there, and... it's been 18 days since the last Lemmy post was received by com.nbb from the communities I'm subscribed to. These might be separate issues...

@Kichae understood, I'll have to take a closer look.

There is definitely an issue, some relays have stopped working but I'm sure the relay is fine.

Stay tuned...

@Kichae there's definitely a federation issue with Lemmy here...

This dashboard shows ActivityPub.Space is just over three weeks behind lemmy.world. Failure count is ~64, which means Lemmy stopped sending stuff over.

I upped my public key fetch limiter value to 512 as well, and will see if this addresses the issue.

@kichae@community.nodebb.org can you try again with the latest develop commits?

A couple things:

• You can now set the rate limit value to 0 to disable it completely
• The logic was a mix of both a db-backed mutex lock and a rate limiter, which was overkill. I think what happened was Lemmy (or other popular instances) sent many activities all at once, causing the rate-limiter to trip, even though the value was well under the threshold.

The default is now updated to 256 but if you've overridden it your value stays. I'll keep an eye on Lemmy federation to see if that was the issue...

If I am right, then within the next 6-24 hours, I should be receiving a flurry of Lemmy content as it speedruns through the backlog.

https://github.com/NodeBB/NodeBB/issues/14422 for updates.

As it turns out I was not right, at least not entirely <img class="not-responsive emoji" src="https://activitypub.space/assets/plugins/nodebb-plugin-emoji/emoji/android/1f61b.png?v=c1f554d6ce2" title="" />

Yeah, I'm not seeing anything behaving differently on develop. My logs are super clean now, though.

@kichae@community.nodebb.org hopefully this will be something that we'll see results on within a day.

Once Lemmy decides your server is "down", it won't send anything for awhile. How long that is I don't know offhand.

@kichae@community.nodebb.org

Heckin' yeah. Update to the latest develop again.

For me, lemmy.world hasn't started re-sending activities yet, but it will... There it goes... 5 million activities an hour hahah

Better, but it's not over yet:

Error rates have crept back up, so there's more debugging to do.
