-------------------------------------------------

Hi Tim,
 I send persistent messages.

This is the test code:

<code>
private void sendALotDLQ(int counter, String messageBody) throws Exception {
                     InitialContext srcCtx = null;
	ConnectionFactory srcConnectionFactory = null;
	Connection srcConnection = null;
	Session srcSession = null;
	Destination srcDestination = null;
	MessageProducer producer = null;

	try {
		Properties props = new Properties();
		props.put(Context.INITIAL_CONTEXT_FACTORY,
				"org.jnp.interfaces.NamingContextFactory"); //$NON-NLS-1$
		props.put(Context.PROVIDER_URL, "localhost:1099"); //$NON-NLS-1$
		props.put("java.naming.factory.url.pkgs", //$NON-NLS-1$
				"org.jboss.naming:org.jnp.interfaces"); //$NON-NLS-1$
		srcCtx = new InitialContext(props);

		srcConnectionFactory = (ConnectionFactory) srcCtx.lookup("/ConnectionFactory");
		srcDestination = (Destination) srcCtx.lookup("/queue/testQueue");

		srcConnection = srcConnectionFactory.createConnection();

		srcSession = srcConnection.createSession(false, Session.AUTO_ACKNOWLEDGE);

		producer = srcSession.createProducer(srcDestination);

		for (int count = 0; count < counter; ++count) {
			TextMessage message = srcSession.createTextMessage(messageBody);

			producer.send(message);
					
			System.out.println("Sending: " + count);
		}
	} finally {
		if (producer != null) {
			try {
				producer.close();
			} catch (Exception e) {
			}
		}

		if (srcSession != null) {
			try {
				srcSession.close();
			} catch (Exception e) {
			}
		}

		if (srcConnection != null) {
			try {
				srcConnection.close();
			} catch (Exception e) {
			}
		}

		if (srcCtx != null) {
			try {
				srcCtx.close();
			} catch (Exception e) {
			}
		}
	}
}

>          Issue Type: Bug
>          Components: Messaging Core
>    Affects Versions: 1.4.0.SP1
>         Environment: OS: Windows XP SP2 / Linux RedHat
> JDK: Sun 1.5.0 Update 12 / 13
> JBAS: 4.2.1.GA (Non-Clustered)
> JBM: 1.4.0.SP1 (Non-Clustered)
> DBMS: PostgreSQL 8.2.4 / 8.2.5
>            Reporter: Abel Munoz Alcaraz
>         Assigned To: Tim Fox
>             Fix For: 2.0.0 Alpha, Stable branch

> PRECONDITIONS:
>  A non-clustered fresh installation of JBM 1.4.0.SP1 in a JBAS 4.2.1.GA with PostgreSQL 8.2.4.
> WORKFLOW:
>  1.- Install JBAS 4.2.1 with PostgresSQL in a Non-Clustered environment
>  2.- Inslall JBM 1.4.0.SP1
>  3.- Startup JBAS with JBM.
>  4.- Send 200100 messages (1K each one) to '/queue/testQueue'.
>  5.- Stop the AS
>  6.- Startup the AS.
> POSTCONDITIONS:
>  There are 200100 message references in jbm_msg_ref with page_ord = null (100 belongs to unflushed downCache).
> When you try to boot AS it says: "Cannot load channel x since the fullSize parameter is too small to 
> load  all the required references, fullSize needs to be at least 200100 it is currently 200000".
> This is done (it seems) becouse when I shutdown the server the downCache is not flushed.
