Hm. Not a lot to go on here. How's the CPU load when it happens?
My server's CPU is completely pinned
it's a Ryzen 7 3700X
That one is with the watchdog set to the default setting, if I disable the watchdog, it'll get further, but the server starts lagging to the point of unplayability
I'll send another log with the watchdog disabled
I'm thinking you're actually just overloading the machine. Try lowering your CPU preset in the DH config file on the server
It'll still be unplayble regardless of the thread preset
And removing/disabling DH makes all the issues go away?
removing it server-side makes the issues go away
client rendering works fine
Are you paying attention to RAM usage at all? And which version of DH are you using on the server?
Updated to the latest nightly like 30 minutes ago
Same behavior both before and after?
yes
Interesting that your CPU is pegged at 100% regardless of the preset
oh wait
it's not pegged regarless of preset
but it is unlayable
Because of TPS, or could it be bandwidth related?
my server and client are on the same network on a wired gigabit connection
Right, so not that
oh that's weird
my client is crashing now
I can run both a server and client together on a 3700x here, so that should have enough umpf to deal with it
not sure why it still says server log
Server and client specs

left is client, right is server

hehe
Here's the actual error message from the client:
ConcurrentModificationException: null
from a render thread. I have no idea what that means or what could be causing it, but you have quite a collection of mods - so finding out could take some time
I think the best advice is a /binarysearch
Try a binary search and figure out which mod is causing it.
So disable half of the mods, see if issue is still there, if yes disable half again etc etc until you find the mod that's causing the issue.
That crash didn't occur until the latest nightly
I forget what version I was using before, but it was another nightly
Maybe @James Seibel GMT-5 has some idea of what it might be
I get holes like this alot

I'm noticing this stack trace quite a bit, but only when DH is installed, wonder if it's related:
What is Ars Additions?
That's the thing C2ME is complaining about here
DH shouldn't be able to cause holes in vanilla MC like that unless there is some sort of mod conflict.
Looking at the logs there isn't anything that immediately jumps out as being wrong on DH's end.
My theory is that Distant Horizions is overwhelming the server's ability to load chunks and it's waiting on processing a ton of chunk load requests, but I'm just guessing based off of the behavior I'm seeing
DH reads the world files directly. It doesn't go through vanilla code. So there are no "requests" from DH to fulfill
