Problem Server Crash on startup - Logs inside

[Kotoma]

Hello!

I have been running this server for a week. We are about 4-5 active players and have our own islands.
Over time the server has been lagging/skipping ticks and I don't know why. But now the server won't even start back up again. Please help!

Ick. That is certainly a strange crash log. For now, have you tried backing up all save files (world save, player data), then reinstalling the server from scratch? The only things I can see are that BiomeTweaks is disabled for some reason, and enderio found some odd behavior in some of the api loading.

Are you running sponge or something like that?
