All The Mods 3 Server doesn't start

in like 4 out of 5 tries my all the mods 3 server fails to start. The last line is almost always:

[Server thread/TRACE] [FML]: Sending event FMLPostInitializationEvent to mod thaumcraft

it doesn't have to be thaumcraft, last time I checked it was enderio

there is no error message, it just stops

now it stopped at [Server thread/TRACE] [FML]: Sending event FMLModIdMappingEvent to mod forge

full log

I just tried, it didn't work. The log still doesn't show any errors.

i wouldn't ask here if that fixed it
