Well it looks like lava is interfering with the generation of a dwarven mine. Although, I'm confused as to why the dwarven mine is attempting to generate in the first place, because none of the seven players online at the time of the crash were anywhere near this dwarven mine.

I assume when you try to restart the server it crashes with the same error.

If I had to guess what was causing this, I'd say the Thermos jar. I would try running the forge jar and going to the coordinates of the dwarven mine ( 35226,19,17552) and see if it crashes.

Of course, remember to take backups before you do anything that could destroy your world.
