I Just changed the permgen to 468 and its still crashing i don't think its a memory error and has the exact same console log
 
you might want to update your server download from FTB because the client buildcraft, ender io mob amputation, pnematic craft , botainia and realistic pain have more updated versions in the client then the server

Ehh bro i think you are running wrong version of the server?
 
I had pretty much the same problem. I don't know if it helps but I had to change in the server properties where it say what world to load' to either the H@rdCore or EasyCore. I chose EasyCore and all work fine after that. But I am using Creeperhost.
There were 5 choices for me:
World - this choice doesn't work, crashes every time.
EasyCore
EasyCore 1.2.5
H@rdCore
H@rdcore 1.2.5
Hope this helps.
