I am using Active MQ 5.13.1 and Master/Slave Active MQ topology configured.
Slave node is getting stopped when database switch happens.

<-- Wrapper Stopped

Tried following auto reconnect configuration, from activemq.xml but no luck

     <persistenceAdapter>
                   			
    			<jdbcPersistenceAdapter dataDirectory="activemq-data" dataSource="#mssql-ds" lockKeepAlivePeriod="5000" > 
    				<locker>
    					<database-locker lockAcquireSleepInterval="30000" />
    				</locker>
    			</jdbcPersistenceAdapter>
    		</persistenceAdapter>

Hello,

in https://issues.apache.org/jira/browse/AMQ-3654 they have suggested using 

 
<databaseLocker>
      <lease-database-locker/>
</databaseLocker>

Yes, lease-database-locker with jDBCIOExceptionHandler resolved the issue.

I see a new issue after implementing lease-database-locker.
Issue: with new configurations, messages are piling up when we switch ActiveMQ nodes.
observations:
1. messages are getting accumulated in one particular queue only and dispatched queue section has pending messages.
2. not observed issues with other queues
3. tried with queuePrefetch = 1, but still observed pending messages in dispatch queue. Consumers were not processing msgs.
