Hello Ron, Please find my comments below. Issue 1: On providing invokerDestructionDelay=10000, my system run out of threads. I mean my client side. Every call results in the creation of new thread, it seems old invoker thread is not getting reused. Secondly, even if I'm working on windows; I'm not creating new sockets. I'm just placing a call to SLSB, now if it creates new socket or thread for each & every request, I think can only be treated as design issue.
