New Forge 1.7.10 server automatically exiting using only Optifine [SOLVED]

Cogitation · September 3, 2015

If anyone can please help, it would be very appreciated. My friend bought Minecraft to play with me on a multiplayer server and we're both disappointed it's not working right now other than without mods (which are most of the point.)

I'm using a newly set up 1.7.10 forge server. My friend was able to connect to the forge server running with an empty mods folder (though we had constant "can't keep up" errors, sometimes as long as 10,000ms.)

Here's the list of mods I was ORIGINALLY trying to use:

Adventure Backpack 2.0.4

Battlegear2-Bullseye 1.0.8.1

Better Dungeons 1.0

BiomesOPlenty 2.1.0.1387

BSpkrsCore 6.15

Dense Ores 1.6.2

Enchanting Plus 3.0.2

Extra Tinker's Construct 1.4.5

Fastcraft 1.21

Flat Signs 2.1.0.19

Fpsplus (latest for 1.7.10)

Infinibows 1.3.0.20

Inventory Pets 1.3.2

Inventory Tweaks (latest for 1.7.10, someone said this is not a server mod, so removed from server)

JABBA 1.2.1a

Journey Map 5.1.0

Mantle 0.3.2

Mystcraft 0.12.3.00

Natura (latest for 1.7.10, don't have it at hand)

Optifine HD Ultra C1

Project E (ie, Equivalent Exchange 2 for 1.7.10, latest)

Tinker's Construct 1.8.7

Thaumcraft 4.2.3.5

Twilight Forest 2.3.7

I've added and removed different mods, trying to see which is the problem.

I know for a fact it won't run with Optifine, EVEN BY ITSELF. Other than that, it seems to fail just randomly.

The exact error I'm having is that the Forge server window comes up, everything loads, and as soon as it should finish loading, the window just disappears, as if it crashed unexpectedly.

Here's the "latest.log" from the server when trying to run with all mods active:

Biomes O Plenty works by itself, and I've had problems with other mods alone, not including Biomes O Plenty. Like, if I take Biomes O Plenty out and run it with all the other mods, generating a new world... it crashed again, just now as I tried it.

Here's the latest.log for the run where it crashed without Biomes O Plenty:
