Mod glitch in my server!

Hey so i run a SMP server for a few people and for some reason when certain mods are used they cause only me to be kicked from the server saying "a fatal error has occured, connection has been terminated" but its only me. The problem mostly occurs with decocraft items but are in other mods. Even if OTHER members sit in a chair or a decocraft item it kicks me. But there are no msgs of it left in console besides this
