Hi, I found the info I needed here...
http://www.5341.com/list/56/179233.html
It's the Axis2-generated client code that causes the leak, and
(confirming what Sanjay said) calling cleanup on the client stub seems
to alleviate the problem.
Our main problem was a crash of the Tomcat JVM on an OutOfMemory error.
We observed a memory leak, but couldn't find a cause for this leak in
our server code. It turns out that the cause was the fact that our
server makes some client WS calls to other systems, using (leaky)
Axis2-generated client code.
Sanjay Gupta a écrit :
Hi,
The problem was in the context. I had to call cleanupContexts and
terminate on the context for the memory leak to go away in axis 1.5.1
client code. So either try not create context each time (right thing
to do) or call the above two methods to clean them up after each call.
The best option is to pool the stub which worked very well for me and
gave better performance as well.
Thanks,
Sanjay

Hello,
We've analysed it with Artus Applicare and Jboss profiler. There is
nothing strange for Axis 1.5.
We are using axis on server side and on client side. Both of them
seems fine.
what kind of tuning tool are you using ?
what kind of model are you using?(on client side? on server side?
ADB,XMLBeans...)
Details:
We've used XMLBeans for generating classes. because we're a little bit
familiar with apache xmlbeans and we've had difficulties when
generating some classes with ADB.

Hi Ceri,
Apart from using 1.5 , did you do anything else. I just upgraded to
1.5.1 from 1.4.1 and still see memory leak. Would appreciate any help.

Yes, definitely. I'm using axis 1.5, it works fine and no memory
leak is observed.
I think this library is replaced by axis2 transport jar.

Hi, can anyone tell me if the problem discussed below ("BackportUtil
jar causing memory leak") was ever verified to be a genuine problem in
Axis2 1.4 ?
Was this a one-off report of the problem, or is it know to be a
general/repeatable issue?
And does it definitely go away from Axis2 1.5 onwards?
Thanks in advance.

Since Axis2 1.5.

between the two(backport.jar
and axis core(kernel)), isn't there any system parameter which can be
configured or a way
to configure axis2.xml so as to switch to concurrency framework
provided by jdk5 rather than
using backport.jar, by still maintaining the same version of axis.
No.
