Status update July 4th

Just wanted to let you know where we are with Lemmy.world.

Issues

As you might have noticed, things still won’t work as desired… we see several issues:

Performance

  • Loading is mostly OK, but sometimes things take forever
  • We (and you) see many 502 errors, resulting in empty pages etc.
  • System load: The server is roughly at 60% cpu usage and around 25GB RAM usage. (That is, if we restart Lemmy every 30 minutes. Else memory will go to 100%)

Bugs

  • Replying to a DM doesn’t seem to work. When hitting reply, you get a box with the original message which you can edit and save (which does nothing)
  • 2FA seems to be a problem for many people. It doesn’t always work as expected.

Troubleshooting

We have many people helping us, with (site) moderation, sysadmin, troubleshooting, advise etc. There currently are 25 people in our Discord, including admins of other servers. In the Sysadmin channel we are with 8 people. We do troubleshooting sessions with these, and sometimes others. One of the Lemmy devs, @nutomic@lemmy.ml is also helping with current issues.

So, all is not yet running smoothly as we hoped, but with all this help we’ll surely get there! Also thank you all for the donations, this helps giving the possibility to use the hardware and tools needed to keep Lemmy.world running!

Lemmy has a memory leak? Or, should I say, a “lemmory leak”?

On some of the latest release candidates I think so.

Rust makes holes and that’s how leaks happen

Leaking memory is safe

Rust protects you from segfaulting and trying to access deallocated memory, but doesn’t protect you from just deciding to keep everything in memory. That’s a design choice. The original developers probably didn’t expect such a deluge of users.

I’m calling it - if there’s actually a memory leak in the Rust code, it’s gonna be the in memory queues because the DB’s iops can’t cope with the number of users.

Wait isn’t lemmy written in rust how do you create a memory leak in rust? Unsafe mode?

let mut memory_leak = Vec::<u8>::new();
loop {
  memory_leak.push(0);
}

That’s not a memory leak though. That’s just hording memory. Leaked memory is inaccessible.
