I'd recommend using a memory profiling tool that lists the object counts by class. I think jvisualvm that comes with Sun's JDK will do it, and I know yourkit will. Check your counts before a :reload and again after -- might give a good clue as to what's going on. --Chouser http://joyofclojure.com/ -- You received this message because you are subscribed to the Google Groups "Clojure" group.
