I am in the process of system testing my FBN system. I have main line code which instantiates threads in a loop to simulate multiple clients. After succesfully completing the execution for 15 times(15 threads), I get the exception below for the 16th thread:
--------------------------------
Factory exception: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused: connect
java.rmi.ConnectException: Connection refused to host: localhost; nested excepti
on is:
java.net.ConnectException: Connection refused: connect
at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:567)
at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:185
)
at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:171)
at sun.rmi.server.UnicastRef.newCall(UnicastRef.java:313)
at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)
at java.rmi.Naming.lookup(Naming.java:83)
----------------------
If I ask the main line code to sleep for 5 seconds after every 15 threads, the program runs fine indefinitely.
Any help is appreciated. I guess it is something to do with the maximum amount of sockets opened in my laptop. I am running the rmi server and the client in the same machine.
Thanks a lot.

I am not sure if this helps, since none answered ur question, heres what i feel.
I used to get these errors when i tried to access remote methods, without starting rmiregistry. May be after sleep, or after 15 calls, there's something happening there, which is disabling the start rmiregistry.
or I think, if u have RMIsecurity Manager on the server side then put it on the client side.
sri.
