During this period, there is constant large stream of messages being send. i tag each message with a Number ID. i notice that some message is lost.. To my understanding, the connection is TCP/IP. i did a script to make the client fallback quickly to server after it went back online again. the old "lost" messages then are send to the client. i believe the network bridge is not yet established when i fall back the client. but not all the messages are accounted.. Can anyone shed some light on this two matter. =) cheers dan -- View this message in context: http://www.nabble.com/Clients-failover-in-HA-mode-tp18148129p18148129.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
