Having feed set to 'Hot' in both Subscribed and All show posts that are over 7 days old and not updating.

I believe it's a bug in Lemmy itself that will be rectified in the next release. For now, like you say, just use 'New'.

Just a heads up, it looks like there's an incredible uptick in development contribution to Lemmy and jerboa for Lemmy, so the next updates might not be far afield and specifically for jerboa the next version seems to fix a wide range of different bugs that people have been vocal about.

Ask your instance admin to restart the instance. It's a known bug. I've set our instance to restart every 4 hours since it takes about 20 seconds to do a restart and is way better than having a stale timeline. That said, SIJW has thousands of users while we only have 200. We can get by restarting, maybe with more users there will be more of a negative impact even if it's only for 20 seconds every 4 hours.

Sorting by top help shows better posts, hope that helps.

I switched to Top- Day, which helps. Still some stale stuff, so I switch to subscribed plus new every once in a while.

I asked and @[email protected] gave it a try. Looks like it's helping but idk if will need repeating.

I'm seeing 9 days old, it's really stuck.

There is an open bug about internal crashes within lemmy_server: https://github.com/LemmyNet/lemmy/issues/3076

A restart of the lemmy_server service might get it fixed for one-time.

It's because of the huge amount of activity last week. Followed by a cooling off this week. The hot Ranking might become admin configurable in the future.
