Hi all, We sync our software by using two brokers installed and configured on the separate machines across the internet. We have a broker A on our linux server and broker B installed on the remote site (Mac). Broker B is references using dyndns service. Broker A is embedded into a Java webapp and broker B is stand-alone, using jsvc. Both brokers are 5.6.0.
Broker A has a network connection to broker B like this : <networkConnectors> <networkConnector uri="static:failover:(tcp://<address>:61004)" /> </networkConnectors> Broker B has a network connection to broker A : <networkConnectors> <networkConnector uri="static:failover:(tcp://client.dyndns.org:61616)" /> </networkConnectors> The problem : everything works fine until at some point when messages start to get dropped (not sure what's caousing this). I can see in our app log that messages are sent (logging is immediately after producer.send(), but no messages are received on the remote site (broker B). Remote app does not log any received messages. After we restart the whole system, it starts to work again as expected. Could it be that : 1) Dyndns system is causing trouble? Anyone had problems with this provider & AMQ? 2) Network connectors are mis-configured (some parars like TTL, maxReconnectAttempts should be explicitely set)? I added failover because I don't want to pollute log files. 3) There's no 64-bit binary ready for Mac 64-bit? I see a warning in the wrapper.log like this : WARNING - Unable to load the Wrapper's native library 'libwrapper.jnilib'.
