My server keeps crashing, Please help

You use he mod thaumcraft?, i read the log and the event FMLServerStopped, (basically the action of the server crash), happend when attempt load the mod thaumcraft, try enter on the server deleting the mod from the server

I need investigate more, sorry but your world its broked for ALL TIME, why? this mod get a block in the generation of world, if you delete the mod and block of this mod stay on the world crashes, and in ALL WORLD, get blocks of this mod, beacuse the world generates whit this mod, your world is broked, sorry :(, or not!, i cant help you if you use this way, but if you install again the mod on the world, and get a wayfor not crash this mod, you can play this world, well, probably if you get a way for fix that, probably for the unistall, the world its broked, you probably you just waste time, and its better delete the world and start other, if you can enter the world, pu in the chat /seed, for get the same world, but whitout the thing you make, and WHITOUT THE MOD OF THAUMCRAFT, and you can start again, im sorry very much,

Well, hehe you are the egnieer, beacuse that probably you know more information than me, but i dont look nothing of this mod, and even so, I have already said it, the mod that said to erase, (thaumcraft), generates blocks in the world, so if you uninstall it, it will have caused corruption around the world, I think it has no solution.

Ok you do not understand me definitely, surely you know more than I do, but from what I understand, if you want to delete a mod that has ALREADY GENERATED BLOCKS IN THE WORLD, you cannot do it, because first you would have to remove all the blocks of x mod to avoid corruptions, (something impossible, if you have generated many chunks and if you do not let him enter the world).

Hmm, i dont know that, good then is other thing.

I looked the log again, and i look, the mod thaumcraft is called again, and when is called, is for call error, error thaumcraft..... error thaumcraft...... 641 errors whit the mod thaumcraft, i think, the forge dont delete the things of the mod, and now the world is corrupt, but well, i looked and you know more than me, then tell me why are 641 errors of thaumcraft. Oh yes the log what i looked is the second.
