end of stream error

I'm using a multitude of plugins and most people don't have any problems, but every once in a while users will get this when logging in.

Code:

I don't exactly know whats going on, or even which plugin is throwing me the error and throwing people from the server. I suspect its AuthMe, but I can't be sure. Any help is appreciated.

I am using the latest bucket build #1000
on a Windows 7 Machine with 5 gigs of ram and a 3.0 quad core processor.

 

Shameless bump for a little help, still getting this problem, haven't gotten a reply yet. I think I have all the information anyone would want.

bump for a bit of help again

Deactivate your plugins half at a time. It shouldn't take you too long to locate the trouble file.

 

Bump i also want to know how to fix this

 

If I'm not mistaken, I heard that this happens to the vanilla Minecraft servers.

 

its really odd, after a bit of testing, I can't seem to locate which plugin is throwing the error at me. It could be a multitude of clashing plugins at once but I can't seem to figure it out. It seems to happen randomly for no apparant reason. Sometimes when people first login it will happen. Sometimes they'll be on for hours and it will happen. Sometimes they'll be repeating the same action over and over again i.e. building, even with the same type of blocks for two hours straight on large builds and it will do it. It just doesn't seem to make any sense. What I did today was reinstall Java, hoping that possibly it could be an actual java error. Well here's to crossing my fingers.
