Hello *Sathish*,

You are probably right!

I have used VisualVM to evaluate it. 

(1)
I have evaluated s:cache. 1 hour measurement with treeCache
Heap Size 108MB -> 190MB after GC
PermGen  108MB -> 111MB after GC

(2)
I took off s:cache, I got not concurent exceptions  :) . 30 minut evaluation
Heap Size 113MB -> 130MB after GC
PermGen  105MB -> 107MB after GC

Seems like a leak. I have JBoss 4.2.3 so I upgraded jboss cache and jgroups (1.4.1.SP14)

Here is what I get now
(3)
I have evaluated s:cache. 30 minut evaluation
Heap Size 115MB -> 127MB after GC
PermGen  105MB -> 111MB after GC

Seems better..

Look here for more
