Server crashes when encountering a corrupted chunk

Hmm, as you're playing on Realms, debugging is a bit difficult. But if you could download and attach the affected (zipped) world file, that would be very helpful. If the file size is too large, please upload it somewhere else and then link to it here.

Hi, thanks for quick response! 🙂

here is a world you asked for.
https://drive.google.com/file/d/1spSmDmv1z5GDniM5mP83igfdTYctrRDX/view?usp=sharing

on single player sometimes this world 'works' - fps drops to 20 near sorter - and sometimes its not loading at all that part.
please take a coordinates of my village from screenshots : )

Ouch... I looked into this. This seems like a very severe case of world corruption.

If you're looking for a quick solution, unfortunately the only thing I can think of is resetting the entire region the corrupted chunk is in.

This is an error message I got when loading the world:

Saving oversized chunk [5, 17] (1405346 bytes} to external file <.minecraft path>\saves\Kalokagathii (My upload)-2\region\c.5.17.mcc

I was able to confirm that getting near that exact chunk (5,17) will crash the server by setting my render distance to 2.

I've attached both the debug profile and the debug report while playing in that world too, perhaps that will be helpful to the developers too. Though I wasn't near the corrupted chunk when they were created. They seem to suggest that the server lag while playing in thar world stems from massive block entity lag.

yea i kwnow there is a little bit more of redstone - hoopers and chests - there  and i was thinking if it could be a problem? is there any limitation on that that i should consider next time ? : )

also " can think of is resetting the entire region the corrupted chunk is in." how can i do that?

its just reseting whole world or just those chunks that have problem?

There should not be a limit on that. The issue is that the chunk file seems to have become corrupted somehow, and crashes the server.

I just tested this again, and just deleting the c.5.17.mcc file in the region folder inside of the world folder should completely eliminate the issue. Note that the affected chunk will be completely reset and generated anew though.

Can you tell us a bit what the contents of this chunk were? The coordiantes of it are 85 / 285.

in that place i have probably kelp farm with design of ilmango:  https://www.youtube.com/watch?v=8kho1aVOsTo&t=867s

60 block long - and that position was in the middle somewhere

@unknown, can this still be reproduced in 1.18.1 or later?

Hi, sorry but i can't reproduce that issue as i dont have realms anymore 🙂

The World file does not seem to exist anymore, could you please provide a new one so that we can reproduce the issue
