Are there any Discord servers or somewhere in the Matrix to chat about hosting a Lemmy instance? I’ve got Lemmy running, but I think there are several of us in the same boat struggling with federation performance issues and it might be good to have some place to chat real time.
My server is struggling with federation. Pretty much everything I see in the logs with debug turned on is this:
2023-06-20T01:55:28.018419Z WARN Error encountered while processing the incoming HTTP request: lemmy_server::root_span_builder: Header is expiredThis is exactly what I am seeing. I just tried upping federation_worker_count in the postgres database. I saw someone in another thread mention trying that so we’ll see.
There is an nginx setting you can tune as well. I believe it was worker threads? Can’t remember the exact one and too tired to ssh into my instance to check.
This post says that the worker threads only effect outbound federation. I’m struggling with my instance not receiving anything inbound.
Upping worker count significantly reduced those in my case. If Lemmy is maxing out your CPU too much though by chance, you may need to upgrade.
