Error "Too many channels open" if a scoped-context is used in EAP6

Issue

• How do I handle a client with a scoped context in a correct way
• If a scoped context is used to connect a remote EJB there is an error if the load increase:

The related code looks like this:

final Properties props = new Properties();
// mark it for scoped EJB client context
props.put("org.jboss.ejb.client.scoped.context","true");
// add other properties
props.put(....);
...
Context jndiCtx = new InitialContext(props);
try {
      final MyBean bean = jndiCtx.lookup("ejb:app/module/distinct/bean!interface");
      bean.doSomething();
} finally {
  jndiCtx.close();
