My client always crash whenever I join my own server but not when I only join a single player world. I have read the the log and I saw a lot of errors of some mods but it's only error for missing dependent mods. But the thing is I found the error which I don't know what it means.

Here is the text log. I cut it down to one report because the whole file is 192MB which contains repeating crash reports generated by this mod.
