So I would suggest, you change that code above to register that interceptor only once per EJBClientContext. Without knowing/seeing more context for that code of your application, I can't suggest where/how to do that such that it registers it only one per context.
{quote}

I see 2 ways to fix that application code.

First:
{code}
/**
   * Get service needed authentication
   * 
   * @param userContext
   * @return
   */
  public T getService(final String fullUserId, final String applicationName) {
    try {
      final Properties ejbClientContextProps = new Properties();
      ejbClientContextProps.put("org.jboss.ejb.client.scoped.context", "true");
      final Context initialContext = new InitialContext(ejbClientContextProps);
      // find the EJB client context which is scoped to this JNDI contet
      final EJBClientContext scopedEJBClientContext = initialContext.lookup("ejb:/EJBClientContext");
      // register the interceptor against the scoped EJB client context
      scopedEJBClientContext.registerInterceptor(0x99999, new ProxyInterceptor(fullUserId, applicationName));
      return (T) initialContext.lookup(jndiName);
    }
    catch (NamingException e) {
      LOGGER.warn("Service non disponible : " + jndiName + ", " + e);
    }
    return null;

  }
{code}

See the way the scoped EJB client context is obtained and how the interceptor is now registered against that specific one.

*Second (the one that I recommend) * is that you create a META-INF/services/org.jboss.ejb.client.EJBClientInterceptor file which contains the following:

{code}
com.inovelan.cloud.common.proxy.ProxyInterceptor
{code}

You can then completely remove the part in your code where you register a client interceptor, since this interceptor now gets registered automatically to the interceptor chain of the newly created EJB client contexts. So your code would then just be:

{code}
/**
   * Get service needed authentication
   * 
   * @param userContext
   * @return
   */
  public T getService(final String fullUserId, final String applicationName) {
    try {
      final Properties ejbClientContextProps = new Properties();
      ejbClientContextProps.put("org.jboss.ejb.client.scoped.context", "true");
      final Context initialContext = new InitialContext(ejbClientContextProps);
      return (T) initialContext.lookup(jndiName);
    }
    catch (NamingException e) {
      LOGGER.warn("Service non disponible : " + jndiName + ", " + e);
    }
    return null;

  }
{code}
