Server-crashing lag spikes when flying over pregenerated chunks
I'm at a loss here... my world is pregenerated up to 20kx20k in the overworld, but whenever someone flies over an area that isn't currently loaded the server starts dipping down to 2-3 TPS and unless they stop loading more chunks the server will eventually crash (without producing a crash log). I've removed all performance related mods besides lithium and it still happens. Anyone have any hints based on this spark profile?

It looks like this happens mostly when flying over oceans,
Try using
/spark profiler start --only-ticks-over 150
Will give better insightman, whole server just crashed because I was alone flying over an ocean
ok one sec
What’s the crash error
there is no crash error

Do you experience rollbacks in progress
yes sometimes
Looks like aether mod is at fault
not sure why tho
yeah
I saw that before and brought it to attention in the aether server, they seemed to think it was just putting the regular server ticks under aether mod for some reason
actually yeah that is a possibility
are you using a hybrid?
so you’re saying there’s nothing in the latest.log when it crashes
it just stops outright?
well, it says server watchdog shuitdown after a tick took 60 sec
let me see if I can turn that off
send that log
You can set max tick time to -1 in server properties but that will result in it indefinitely hanging
And even with a semi-bad cpu like that, it shouldn’t happen
that log is useful though
here's the latest

oh ok one sec
ok here's the server log and I also have a crash report coming https://mclo.gs/3UY3w4b
Oh sorry can you send the actual crash report text file
Send this pls

hmmm
Make sure lithium and permanent sponges are up to date
c2me too
I thought it was related to c2me but happens without it
let me check the others, we dont even use sponges tbh
They’re all up to date. Try remove permanent sponge if you can
I've deleted permanent sponges from server and client let's see after I restart here
Take a backup beforehand
alright
backup isn't fast, this world is 170gb lol
deleting permanent sponges seems to have done something, actually I was flying over a coral reef when it crashed
Holy shit. sponges lol
Ocean chunks aren't loading well but it's not dropping TPS
I probably would have torn the server apart before deleting a sponge mod
Apparently it was sponge mod. Besides lithium and C2me, any server side optimization mods you can recommend?
