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.
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.
