So I've been running into an issue where the server will lag horribly, eventually freezing all together and getting shut down by the WatchDog for excessive tick delay. It seems to happen whenever someone on my server goes after an ice dragon in a lair, though it has been known to freeze randomly when exploring and when entering certain areas. We've tried removing a couple mods that could be related to the issue, but no luck. This is happening even while the server isn't using the full RAM or CPU available to it. This is the crash that happened when we had all our mods. If anyone has any ideas I'll take 'em.
So what am I looking for exactly? I tried turning off watchdog and had my friend return to the spot, the server froze completely. It didn't even get to crash.
There are plenty of campfires nearby since there is a village at the spot that it froze on. Although, I'd like to mention it doesn't freeze immediately. If I had to make a guess it would be the server destabilizing from something. I logged in multiple times each going a different direction from the spot, and it still freezes.
Additionally, it might not be the campfires. Here's a crash report before the one I posted earlier; https://pastebin.com/Vh3Tvqpq
I believe it's a different spot from before, but even still showed similar symptoms.

You can disable watchdog by setting max-tick-time to -1 in server.properties
Before, create a Backup
Then check that location

Check for something like a CampFireBlock

I think one of your mods causes issues - I have no idea which one
I'll try testing mods in small groups to see what could be causing it then. Thanks for the help.
