Lemmy upgraded to 0.18.5 (self.main)

Lemmy is now upgraded to 0.18.5! This is a much needed bug fix that fixes federation of admin actions.

Unfortunately the server crashed when shutting down nginx (wtf), so there was about 5 minutes of downtime as I hopped onto the console to power cycle it. This is the second time that's happened now, so further investigations will be had =)

I probably only noticed because I'm on it too much, that was very quick 😄

Can confirm that the status.lemmy.ca page worked nicely when I went to check what was up

nginx can crash?!

But seriously, this instance uptime is awesome. 5 minutes late on a Friday night is barely noticeable 😀 thanks for your excellent work!

Was actually a whole kernel panic, it looks like all IO on the box completely hung when the nginx docker container was stopped. Kinda a mystery, wondering if it's a kernel bug.

Oh damn! What kind of memory usage and open file handles does nginx typically use for this instance?

Our usage is really low across the board. I've thrown as much ram at postgres as its willing to use, and right now after a clean boot we're only using 4gb of ram.

Other than some poor sql, lemmy is actually really performant. There's a lot more attention on the db now though which has helped a lot.

I'll try to do a post this weekend with some data graphs.

That would be awesome! I'm glad to hear that Lemmy is performing in general and that the SQL woes are being addressed
