I have an account on feddit.uk and lemmy.world with almost identical subscriptions.

When I visit the feddit.uk homepage and look at posts from my subscriptions sorted by “hot”, the two posts immediately after the two pinned Feddit UK posts at the top are 6 days old. The behaviour with “active” is similar. Posts shown are quite old, and neither hot nor active.

When I visit the lemmy.world homepage and look at the “hot” posts from my subscriptions, the first 10 are all with the last couple of hours. Active shows posts in the last 24 hours with a healthly number of comments.

Both servers are running 0.17.4

Basically, right now feddit.uk is almost unusable for me due to both hot and active being populated by stale posts. I need to search by “new” to get anything approaching useful - but when I do that there is just too much to sift through.

    I get this a lot. Hot posts 4 days old with no new comments. Something isn’t quite right yet.

    I’ve also noticed this.

    I’ve also noticed that when I leave the front page open in subscribed view I occasionally get a sudden flood of posts appearing, they’re always from remote instances and normally older posts (sometimes a few days old). It kinda looks like they’re only just being received by our instance at that point, although I’m not familiar enough with Lemmy to say thats 100% whats happening. But if we’re not reliably receiving posts then that could explain why the front page content is stale.

      I think you’re right, but the fact that lemmy.world appears to work and is also on 0.17.4, may imply an additional issue (although I appreciate the problem not occuring there may simply be because it’s not 100% reproducible).

        Not sure if it helps but these are the first 4 “hot” posts I can see after the two pinned ones:

        Although a day or less old. So that seems to be working as intended for me. I do know “active” is an issue that 1.8 is designed to address. No ideal why lemmy.world doesn’t have those problems.

    I was reluctant to upgrade to v18.0 because it didn’t have captcha but I’ve decided to upgrade it anyway and close the registration to of the instance behind a question to avoid spam instead

    @tom@feddit.uk Hey Tom. This issue is persisting for me. I get the odd post that I would consider hot, but in general the posts are days, weeks or in a couple of cases YEARS old! I have accounts on two other instances with similar subscriptions to those I have here:

    lemmy.world doesn’t have this issue (although it has many other issues and is generally unusable, I think due to load). They are on UI: 0.18.1-rc.7

    programming.dev is also on BE: 0.18.0 and seems fine. No issues with hot posts. They have about twice the number of users/posts as feddit.uk.

      Hey, that is very weird and one I can’t reproduce myself unfortunately.

      I think all I can do atm is wait for the full 0.18.1 release and hope that fixes it otherwise will need to dig into it further

        Stranger and stranger… these are my “hots”. They start off okay, and then quickly they are a year+ old. Happens on all clients. I’m probably going to create a new username/account and see if it’s the same. Maybe something has got stale with this one. Besides, I don’t like my username anymore! :)

          Yeh I think that might be best creating a new account let us know if that has fixed it

            Sadly, it’s not fixed it. Although I’ve noticed it’s community specific…

            I think I got rate limited when I used a python script to migrate my subscriptions (some 503 errors) but most of them came through. My new account still gets this post from a year ago (https://feddit.uk/post/321952) as my 4th hot post. Along with a number of 1 year+ old posts below. However, after looking into it looks like they are all from Programmer Humor@lemmy.ml. Going back to my original account, which has my full subscriptions, again they seem to be from some specific communities:

            ADHD memes@lemmy.dbzer0.com
Programmer Humor@lemmy.ml 
Gaming@kbin.social 
Gaming@lemmy.ml
CasualUK@kbin.social 
Cathode Ray Tubes@kbin.social

            I’m going to unsubcribe from these for the time being, and see how I get on.

              Hmm it might be an issue with the communities then or the way they are stored in our database. I’ll have a look and some test accounts, subscribe to those communities and see if I get the issue as well

      I reckon something is just broken (at least for me). This post about lettuce has been my top hot post for days both on the web and via two different apps…

        Just taking a cursory look at the code, it appears the ranking of posts per sort is stored in the database routinely via a background process on the server: https://github.com/LemmyNet/lemmy/blob/main/src/scheduled_tasks.rs#L31C10-L31C10

        So, could be to do with that. If the server is underprovisioned, maybe it’s taking an overly long time to run each calculation and everything is being held up. Complete speculation, though, at this point. 🤷

        Edit: this is actually the 1.8 version of the code. Prior to this it looks like this was being done differently (see: https://github.com/LemmyNet/lemmy/pull/2952/files). So like Emperor says, it looks some optimization work was done here as presumably the queries were running too slowly.

    Yes, this server is crap. Stale posts everywhere, server is not updated. What a joke.

      Not being updated to 0.18.0 is fine though. Lemmy.world is still on 0.17.4, as are many others. 0.18.0 doesn’t have Captcha which had to be enabled on feddit.uk last week due to a flooding of bot registrations. Apparently it’s retuning in 0.18.1.

      However, sadly I’m finding it unusable right now with the sorting, so I’m mostly on lemmy.world ☹️

    @tom@feddit.uk Any idea if there’s anything that you can do about it? It does make the place pretty difficult to use and enjoy. I’d like to keep this as my main Lemmy account, but at the moment the other big instances are much more usable due to the functioning feed sorts.

    My top 13 results in All > Hot are currently 10 all days old…

      Commented above but I’ve updated to v18.0 so hopefully that fixes it

        Thanks Tom. I think Lemmy’s “hot” sorting is still bums, but that’s not feddit.uk’s fault. I posit that posts with no comments should not be considered “hot”!

        Looks like this issue has returned, at least for me. And even worse! I’m now getting 2 year old post appearing as my top “hots”.
