Document - consumer.close() method should not depend on MaxRetry attribute when trying to read messages from a node which is disconnected from DB

A node fails to read all its messages if disconnected from its database. This happens because the node fails to acknowledge messages on database disconnection. To avoid the problem, set the node parameter <parameter>MaxRetry</parameter> to a value greater than <literal>-1</literal>. You can set the attribute value in the MBeans <classname>PersistenceManager</classname>, <classname>PostOffice</classname>, and <classname>JMSUserManager</classname> in the file <filename>[database]-persistence-service.xml</filename>. The Messaging User Guide now contains details about the MaxRetry parameter, and how to configure it in conjunction with other related parameters.
