Dedicated server starts lagging seemingly randomly [1.16.5]

[EnderMelody]

Been running a dedicated server for a while, and after an update it started lagging a lot. Getting spam of 'Error adding element: Base value out of range: 256 [-10-128]' in the debug. This seems to occur after biome generation is edited, which causes the process to reset and repeat over and over. We can play for a while before this happens though.

I don't see any trace of that error in the log you provided, is that the complete log? Also, you said, after an update it started lagging..did you notice this after updating a specific mod?

It seems like github cut off the log because it was too long, so you cant see the error because it is further in the log. I have looked into it further and believe it is 'mowzies mobs' causing the problem, though im not sure yet.

here is a snip of the log, and if you have a better place to upload it that would be great:
