Dear Bharat,
I have observed the same behavior. Allow me to present the details u seek.
Server:
Created a Sample HTTP Service with CXF 2.0.3(publishing Greeter interface
provided in sample )
Service was published using :
Endpoint ep = Endpoint.publish("http://localhost:9000/Greeter";, new
GreeterImpl());
and GreeterImpl has "String greetMe(String me)" which just returns a string.
Server is running on a Solaris 10 machine with java version "1.5.0_14"
Server does nothing else.
The libs in classpath are
-classpath
lib:/lib/cxf/asm-2.2.3.jar:lib/cxf/commons-logging-1.1.jar:lib/cxf/cxf-2.0.3-incubator.jar:lib/cxf/geronimo-activation_1.1_spec-1.

Server is run with JVM parameters "-Xmx129m -XX:MaxPermSize=128m ". No other
tuning parameters added in server[However, a lot of other tuning were tried
(like, -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled) and found that the result is not favorable]
Client:
Client written in CXF, sends requests continuously to the server.(infinite
loop)
Behavior:
The memory of the server continously increases from ~90M to ~350M which
never comes down.
But through jconsole we know that the Heap, or non-heap memory hasn't
increased much.

Same test was carried out with CXF Version 2.1.2 and it behaves the same
way.

Please help us identify the reason for this mem increase.
