[jboss-dev-forums] [Design of JBoss Serialization] - Using customized RMI socket factory with JBOSSSerialization
Hello all,
We are trying to imrove RMI performance in one client-server RMI application. we
customized RMI socket factory (client and server), which uses customized Socket and
ServerSocket, which use JBOSSObjectInputStraem and JBOSSObjectOutputStraem (is this the
correct way to use jboss serialization in RMI?).
One flow in the client application invoke many time Naming.lookup() on the server rmi
registry.
If not using the customized socket factory (hence not using jboss serialization) -
everything works great. If using the custmozied socket factories, OutOfMemoryError is
raised:

Can you please assist with debugging this behaviour?
Thanks,
