RAM usage increasing, eventually running out.

Hey, is there a plugin or mod that allows me to view how much RAM each plugin is using? Or something similar...

Ever since I updated to 1.2.5 the RAM usage just keeps going up and up and up until it pretty much gets to laggy and I'll have to restart. It's like JAVA isn't garbage collecting. Used to run fine with 1Gig usage with 15 players on. Now it uses 2gig for 4 players after a couple hours or so...

I have a hunch it's Dynmap doing it. Will be testing the server without it now.


EDIT: It was DynMap. For some reason. Taking up all the RAM. Been settled at 800MB with 8 players all day without it installed.
