This is a problem that has stumped me for days on end, and I know that many people are having the same problem. A fair few of us have encountered the "Too Long" error message, that is lines and lines of errors regarding ModLoader. Thankfully, there is an easy work-around.
This error comes around by there being duplicate mod files in the Mod directory of your server. Simply delete the folder and reload it from the server zip file, and the problem goes away~
I hope this solves a heap of people's problems!
