So I’ve been troubleshooting the federation issues with some other admins:
(Thanks for the help)
So what we see is that when there are many federation workers running at the same time, they get too slow, causing them to timeout and fail.
I had federation workers set to 200000. I’ve now lowered that to 8192, and set the activitypub logging to debugging to get queue stats. RUST_LOG="warn,lemmy_server=warn,lemmy_api=warn,lemmy_api_common=warn,lemmy_api_crud=warn,lemmy_apub=warn,lemmy_db_schema=warn,lemmy_db_views=warn,lemmy_db_views_actor=warn,lemmy_db_views_moderator=warn,lemmy_routes=warn,lemmy_utils=warn,lemmy_websocket=warn,activitypub_federation=debug"
Also, I saw that there were many workers retrying to servers that are unreachable. So, I’ve blocked some of these servers:
commallama.social,mayheminc.win,lemmy.name,lm.runnerd.net,frostbyrne.io,be-lemmy.org,lemmonade.marbledfennec.net,lemmy.sarcasticdeveloper.com,lemmy.kosapps.com,pawb.social,kbin.wageoffsite.com,lemmy.iswhereits.at,lemmy.easfrq.live,lemmy.friheter.com,lmy.rndmm.us,kbin.korgen.xyz
This gave good results, way less active workers, so less timeouts. (I see that above 3000 active workers, timeouts start).
(If you own one of these servers, let me know once it’s back up, so I can un-block it)
Now it’s after midnight so I’m going to bed. Surely more troubleshooting will follow tomorrow and in the weekend.
Please let me know if you see improvements, or have many issues still.
I’ve read about it and I don’t understand. I have a list of the languages in the settings, but I have all of them and I cannot remove or add any languages.
The list is to select from, not what you have selected. If you click one it should highlight it blue. Then hit save at the bottom of the profile.
The dialogue is very bad.
To select what languages you want, hold ctrl and click each language you want, to highlight it.
With the languages you want highlighted, save the settings.
