> A standalone client application is calling EJBs on a backend server through an Undertow loadbalancer.
> The client looks like this:
> {code:java}
>         Properties props = new Properties();
>         props.put(Context.INITIAL_CONTEXT_FACTORY, WildFlyInitialContextFactory.class.getName());
>         props.put(Context.PROVIDER_URL, "http://10.0.0.1:9080/wildfly-services");
>         props.put(Context.SECURITY_PRINCIPAL, "some-user");
>         props.put(Context.SECURITY_CREDENTIALS, "some-password");
>         InitialContext      ctx = new InitialContext(props);
>         String name="ejb:/playground-jar/JBossManIntClientBean!org.jboss.playground.JBossManIntClient";
>         JBossManIntClient bean = (JBossManIntClient) ctx.lookup(name);
> {code}
> A client invoking the same EJB twice result in thousands of requests from the balancer to the backend servers, e. g.:
> * 13468 times: 
> {code}

> {code}
> *Note:* This behavior only occurs if there's more than a single backend server running in a cluster...
