Consider TrueNAS Scale with mirrored drive pairs DIY.

Not sure what you’re using to generate that list/formatting is a bit difficult.

I don’t have a cluster since it’s effectively single user + @[email protected] (in theory a few other people have access, but they’re not active), single machine, it’s just more or less the out of the box docker stuff on a bare metal machine in my basement + a digital ocean droplet.

The droplet is what I’m using to have a static IP to prevent dynamic DNS nonsense + it provides some level of protection against a naive DDoS attack on random fediverse servers (since I can in the worst case, get on my phone and severe the ZeroTier connection that’s using to connect the droplet to my basement server).

I’m pretty confident whatever is going on is payload related at this point.

I’ve got quite a bit of experience with postgres; I don’t see any indication it’s the problem.

So, I think this is a (helpful) general comment but wrong in this/my specific case.

The server is so small it’s not really going to register on a 10-minute frequency for outgoing content – I’m not that much of a lemmy addict! haha.

You can see in a comment here my most recent comment to lemmy.world did sync: https://lemmy.world/comment/8728858

I’m not having any issues with outgoing content, beehaw, the KDE instance, and several others. It’s just lemmy.world that’s acting up (which is unfortunately because it’s my favorite – I mod/run several communities and donate to here/them – haha).

Yeah, I mean things should be fine in general; like I said this has been working for quite a long time now without issue.

The machine that’s actually doing the work here is quite powerful and is used to run several game servers in addition to Lemmy … Lemmy really isn’t much more than footnote in resource usage:

So, I think you’re most on the right track of the responses…

It seems to just be exclusively incoming from lemmy.world. If you look here, my most recent comment is on lemmy.world:

https://social.packetloss.gg/comment/1415801 https://lemmy.world/comment/8710941

The instance just isn’t getting any new posts, comments, or votes back from lemmy.world.

Everytime I shut down the lemmy server I see this:

2024-03-23T17:34:33.774333Z  WARN lemmy_server: Received ctrl-c, shutting down gracefully...
2024-03-23T17:34:33.774912Z  WARN lemmy_federate: Waiting for 1618 workers (30.00s max)

That number never seems to move, there are always 1618 works. I’m not sure if that means anything or not regarding pending processing or what have you.

I am seeing in my publicly facing nginx logs:

There’s then an internal nginx server that sees:

So, things did start timing out. I’m not sure what to do about that though.

This server is not resource starved:

load average: 0.04, 0.09, 0.10

              total        used        free      shared  buff/cache   available
Mem:          31507        7651        1092         164       22764       23239
Swap:         16087           1       16086

It’s just this lemmy.world data that’s suddenly out of wack after months of normal operation (both on lemmy 18 and 19).

It feels like a bad payload that the server just can’t move past for some reason and lemmy.world keeps sending.

I had logging on the lemmy container itself piped to /dev/null because it’s just such a noisy log. I turned it back on… I’ll see if I can find more information next time lemmy.world posts.

Yeah I’m basically the only user of this server. Good data point that you’re not having issues though.

It’s been up on 19.x for a few months now. It’s also a full on bare metal server with a ton of resources, it’s not at all starved.

It’s almost like someone posted something to somewhere that “jammed” Lemmy and it just won’t get past it but I’m not sure how to figure out what that would be or how to unjam things.

and that it’s owned by Google.

I mean yes, but it’s patent irrevocably royalty free (so long as you don’t sue people claiming WebM/P as your own/partially your own work), so it’s effectively owned by the public.
