Support Request: SMP logon error

    Okay,
    For some reason whenever my friends try to log on to my minecraft server with industrial craft and buildcraft 2.2.5 installed it gives them this error

    Code
    Connection Lost    	{or Internal the word is cut off} External exception: java.io.IOException: String length of 1953068645 {this number tends to change} is higher than the max (6553)


    Any help with this particular error would be much appreciated! :D

    The string is too long. (I don't know which string that is)
    1,953,068,645 is 1.95 BILLION, a string that long would take up nearly 1.8 gigabyte of memory.
    I also believe the max string length is 65535 not 6535 since representing the value 65535 takes two bytes in a computer. (2^16, or 16 bits)

    With that error given, it's nearly impossible to trace it to a problem. We need more details!

    okay
    The server console says "end of stream" when it kicks someone. Everyone is using the exact same version as mine (i sent them a RAR with the mods in it).

    Code
    Josh joined with mod_BuildCraftCore 2.2.5, mod_BuildCraftBuilders 2.2.5, mod_BuildCraftEnergy 2.2.5, mod_BuildCraftFactory 2.2.5, mod_BuildCraftTransport 2.2.5, mod_IC2 v1.337b, mod_IC2Thermometer v1.15

    and the server start up code is as follows

    Code

    IC thermometer? Version 1.15 crashes on recharge in 1.337b worlds.

    Probably someone tossed a thermometer in to a batbox or something and when it tries to charge it crashes. What happens when everyone removes that or uses the alternate thermometer mod from later in the thread?
