Modded Minecraft Server, Keeps lagging and thereby crashing

[jimkerman]

Hello, me and my friends have been playing a modded Minecraft server together and everything has been fine, however, all of the sudden out of nowhere the server keeps on crashing, I am not sure why. It does not matter where we are or what we are doing. We are running on 1.12.2 with the Latest version of forge for that version, I have attached here a crash report log file. Thank you all in advance for any help received!

Are there changes if you set max-tick-time to -1 in the server.properties?

[jimkerman]

Tried that this morning, but the lag just stuck and I was booted from the server and unable to rejoin until I restarted the server because it thinks I am still there.

Maybe an issue with IC2 or a broken chunk

[jimkerman]

If that is the case How would I go about fixing that? Does the crash log not say what it might be?

[TileEntity]

Maybe try other builds of IC2

Tried a different build of IC2, no change

Backup the world and make a test without this mod

Alright, well before removing IC2 I changed the max chunks from 15 to 6, and that seems to have fixed most of it, BUT, the console log keeps spamming out this "[16:01:09] [File IO Thread/WARN] [FML]: Large Chunk Detected: (11, 19) Size: 578 ./servermodworld2024oct/region/r.5.2.mca", and it is still lagging a little. What exactly does this mean and by some chance is this a chunk I can find and fix? If so how can I find it? After testing the server without IC2, the same error message still shows up, and the server continues to suffer in terms of lag.
