Ron Sigal commented on EJBTHREE-986:
------------------------------------
There appears to be a restriction in Windows on the range of values that can be used for
binding client sockets. See the article at
http://www.microsoft.com/technet/community/columns/cableguy/cg1205.mspx . The default
range is 1025 - 5000, which fits with your observation that the problem occurs when you
use > 3000 connections. You can increase the maximum port to 65534. Yvan, could you
try that and see if it fixes the problem?
EJB3 Remoting cause BindException on load
-----------------------------------------
Key: EJBTHREE-986
URL: http://jira.jboss.com/jira/browse/EJBTHREE-986

Jboss server and test client are on the same host.
For each call, a new TCP connection is opened, with a different local port. So there is
also a performance problem.
Here is a simple code to reproduce :
-- EJB3 remote Interface --
package ejb;
import javax.ejb.Remote;
@Remote
public interface Foo {
public void bar();
}
-- EJB3 Implementation --
package ejb;
import javax.ejb.Stateless;
@Stateless
public class FooBean implements Foo {
public void bar() {
}
}
-- client --
package client;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import ejb.Foo;
public class Test {
public static void main(String[] args) {
try {
Properties env = new Properties();
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
env.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put("jnp.disableDiscovery", "true");
Context context = new InitialContext(env);
Foo foo = (Foo)context.lookup("FooBean/remote");
while(true) {
foo.bar();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
