Yes

Is Modded: Definitely; Server brand changed to 'thermos,cauldron,craftbukkit,mcpc,kcauldron,fml,forge'

Does this happen on a non-cauldron/kcauldron/thermos/mcpc server? (basically vanilla forge)

can you post a crashlog with the forge server?

Broken forge installation. Also no support for any bukkit derivate.
