I'm runnig Oracle 8i on Solaris 7.
I've modified the EJB sample in '../examples/ejb/basic/helloworld' in a way
that the request will be repeated 100000 times. After running this program for a
while i receive the following Java-Exception:

-----THE OUTPUT -----------------------------------------------------
i=1 time=3 ms.  Hello client, your javavm version is 8.1.5.

...
i=50808 time=3 ms.  Hello client, your javavm version is 8.1.5.
i=50809 time=4 ms.  Hello client, your javavm version is 8.1.5.

=================================================
Sometimes it was possible to run the 100000 iterations. But most of the
cases the exception will be thrown between 10000 and 80000 iterations.
Any idea. Is this a known problem?
 

-------- THE SOURCE --------------------------------------
import hello.Hello;
import hello.HelloHome;

import oracle.aurora.jndi.sess_iiop.ServiceCtx;

import javax.naming.Context;

public class Client
{
  public static void main (String[] args) throws Exception {
    if (args.length != 4) {
      System.out.println ("usage: Client serviceURL objectName user password");
      System.exit (1);
    }
    String serviceURL = args [0];
    String objectName = args [1];
    String user = args [2];
    String password = args [3];

    Hashtable env = new Hashtable ();
    env.put (Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
    env.put (Context.SECURITY_PRINCIPAL, user);
    env.put (Context.SECURITY_CREDENTIALS, password);
    env.put (Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
    Context ic = new InitialContext (env);

    HelloHome hello_home = (HelloHome)ic.lookup (serviceURL + objectName);
    Hello hello = hello_home.create ();
    long t = 0;

    for (int i=0; i<100000; i++) {
        t = System.currentTimeMillis();
        String result = hello.helloWorld();
        System.out.println("i="+i+" time="+(System.currentTimeMillis()-t)+" ms.  "+result);
    }

  }
}
