I've got the following problem:

I've got 2 Stateless Session Beans. One of them calls other's method for several (about 10, actually) times. On the fifth or sixth call jboss starts to use something like 35-40 megabytes of memory for call marshalling, and finally application crashes with java.lang.OutOfMemory.

What can be done to avoid such an aggressive memory consumption?

code is something like the following:

 .... we are in method of SLSB A....

bSession = BSessionLocator.locate();
Set somethings = new HashSet();

for(....){
 Object something = Session.getSomething( ...some params... );
 somethings.add(something);
}

.... some other code...

BSessionLocator.locate() is a static method that gets BSession from JNDI

I am using JBoss 4.0.0

Thank you for your help.
