      Description

      After a lot of call (>3000) to an EJB3 SLSB this exception is throwed :

      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(); }

      }
      }
