Axis memory leak

[Vy Ho]

When setting the scope of my service to application, the client side 
will run out of memory after 5-10 thousand hits. The service object on 
the server side is thread safe and works with both application and 
request scope.  The server does not have any leak.

The reason I change it to application scope is that it performs somewhat 
better this way.  Anyway, do I have to do anything special on the 
clientside to clean this memory up, or it's a bug in Axis?  If it's a 
bug in Axis, it should be fixed before the release, because this is a 
huge leak and will bring any serious application down.
