I require assistance! (exp orb problem!)

Not 100% if this is the right place but eh, what the heck. So my friend was helping me build a huge minecart track (25k blocks+) and I was using world edit, so I was teleporting to him and /kill(ing) myself to get back to the other side, whenever I did this I dropped a lot of exp.
Now to the actual point, He had ALOT of exp, so when he died he dropped ALOT of exp, Now whenever we try to do something to get rid of it we pick it up from insane distances. The exp is causing the server to lag tremendously, and we need to know what to do

 

The server actually isn't lagging, Just your clients. If you go far enough away that your client isn't rendering the chunks, the lag will stop.

But since that's a pretty crappy solution, there's two plugins in this thread that can help:
