I don't think you're supposed to run optifine on a server (not 100% sure, but it seems wrong), if you remove it does it still happen?

I dont know if this is what you're trying to say, but my minecraft crashes, not the server.

Forge Essentials aims to provide a suite of powerful fully server-side utilities to make running, administrating and using a server better and easier. This mod only needs to be installed on the server and should not be installed at all on the client.

ForgeEssentials is a server-only mod.

I don't think it needs explaining why you get that error.
