This is a shot in the dark, I am hoping you recognize something in this profile that can help find why the server had locked up a few times.

This started when logging in a player, other players were on the server, the server became 100% unresponsive ingame and on console, until that player quit his client, then it recovered.

net.minecraft.util.math.shapes.VoxelShapeSpliterator.func_234878_a_()70.21%70000ms

byg is the only biome mod in the modpack.

It never crashed, it locked up hard, then recovered.

Here is a zip of the webpage with the warmroast profile.

Warmroast and sampler are the only two things I have found to help diagnose a lockup, unfortunately, sampler isn't updated yet.

Not sure how this is pointing to be BYG issue. Have you tested BYG on its own?

ProsperCraft · Answer 4 · 2020-10-19T04:22:42.000Z

We can't cleanly reproduce it, we can play for days then suddenly it locks hard on that VoxelShapeSpliterator, I was just hoping with Biome in the stacktrace you might recognize it.

Send me the file in this screenshot on google drive. Also Send a latest.log and a crashlog(if applicable) too.

ProsperCraft · Answer 6 · 2020-10-20T01:50:29.000Z

It happened again -

CorgiTaco · Answer 7 · 2020-10-21T07:29:11.000Z

I've been asking around about this but no one cares enough to answer me. This most likely has to do with rendering of some sort.

CorgiTaco · Answer 8 · 2020-10-21T08:20:11.000Z

@ProsperCraft I have an idea of what it might be.... There might be a mod in your modpack that has a block larger than the block space. I read through the code a bit more and it makes sense.... You need to find that mod in question and report to them...

CorgiTaco · Answer 9 · 2020-10-21T08:21:10.000Z

Start with any mods in your pack that might have a piston like block

CorgiTaco · Answer 10 · 2020-10-21T08:25:18.000Z

What I mean larger than the 1x1 block space is like a hitbox/voxel shape is larger than the 1x1 block space. Basically, an oversized block voxel shape/hitbox

Gegy · Answer 11 · 2020-10-21T09:53:28.000Z

Could this potentially be related to the vanilla structuregen deadlock? Might be worth running with the watchdog enabled to catch the state of all threads when locked

CorgiTaco · Answer 12 · 2020-10-21T08:33:40.000Z

Not sure if BYG's tall plants could be causing this... I'll check later today and make sure this isn't the case, bc we should be matching Vanilla's

CorgiTaco · Answer 13 · 2020-10-22T06:51:12.000Z

@ProsperCraft Im assuming you've found a solution?

ProsperCraft · Answer 14 · 2020-10-22T13:57:46.000Z

No, it still locks up.

CorgiTaco · Answer 15 · 2020-10-23T03:00:58.000Z

We'll wait til 1.16.4 and see what happens then... like Gegy mentioned, could be related to the deadlock.

CorgiTaco · Answer 16 · 2020-10-23T03:08:15.000Z

Could be related to the bug patched in 1.16.4: https://bugs.mojang.com/browse/MC-199487

ProsperCraft · Answer 17 · 2020-10-30T18:11:20.000Z

We have not had this issue since wiping the nether and end, will re-open if it happens again.
