Lemmy.world updated to 0.18.1-rc
Looks like it works.
Edit still see some performance issues. Needs more troubleshooting
Update: Registrations re-opened We encountered a bug where people could not log in, see https://github.com/LemmyNet/lemmy/issues/3422#issuecomment-1616112264 . As a workaround we opened registrations.
Thanks
First of all, I would like to thank the Lemmy.world team and the 2 admins of other servers @stanford@discuss.as200950.com and @sunaurus@lemm.ee for their help! We did some thorough troubleshooting to get this working!
The upgrade
The upgrade itself isn't too hard. Create a backup, and then change the image names in the docker-compose.yml and restart.
But, like the first 2 tries, after a few minutes the site started getting slow until it stopped responding. Then the troubleshooting started.
The solutions
What I had noticed previously, is that the lemmy container could reach around 1500% CPU usage, above that the site got slow. Which is weird, because the server has 64 threads, so 6400% should be the max. So we tried what @sunaurus@lemm.ee had suggested before: we created extra lemmy containers to spread the load. (And extra lemmy-ui containers). And used nginx to load balance between them.
Et voilà. That seems to work.
Also, as suggested by him, we start the lemmy containers with the scheduler disabled, and have 1 extra lemmy running with the scheduler enabled, unused for other stuff.
There will be room for improvement, and probably new bugs, but we're very happy lemmy.world is now at 0.18.1-rc. This fixes a lot of bugs.
I had a strange bug today where I wasn't able to upvote comments. So I cleared out my website data like the website suggested and I started having problems logging in. It would log in but then when I refreshed it wasn't logged in anymore. It stopped after a while but then when I clicked on an old tab when I refreshed I was logged out again. So, the log in issue must be something to do with how iOS Safari handles web cache on tabs.
Upvotes aren't responding for me, but the comment is marked as upvoted when I refresh the page. I think it just isn't rerendering on the frontend.
Edit: same thing is happening when posting comments. I refresh and the comment was posted, but without refreshing it's marked as loading forever.
Exactly same thing for me (but on Chrome on Windows), I emptied my cache and I just can't log in (says it worked, but it really doesn't)
I had the same issue with Firefox on Linux. I had to clear website data again to fix it.
I had the F12-mode open to see what was going on with cache disabled, so that might have helped as well.
I’m having major issues with upvoting in safari on iPad. Seems like it will take either 10 seconds or so and work or not react at all.
Edit: Wiping all safari browsing history/clearing everything fixed it for 20 mins or so and it’s back to behaving the same way again.
I suddenly got "logged out" again, but when I opened a new tab and went to Lemmy.world I was still logged in.
@Tag365 @Tag365 You prolly ended up in another instance (lemmy.x)
Wrong, it was the same instance, merely the tab was unloaded and then reloaded.
