Broker A comes up and tries > to connect to broker B, which is not functional yet. The Discovery Network > Connector at A adds service B to its tracking state "bridges" (list of > connected services) before activating the connection. However, if there is a > failure, the data structure is not cleaned up. When the DNS Discovery Agent > module rescans (DNS) and passes on uri for B into DNC, it simply ignores it > (as its tracking state hasn't been cleaned up upon prior failure). > The attached patch should take care of this issue (in the observed code path) > - test log below: > 2006-09-11 15:36:11,810 [main ] INFO > network.DemandForwardingBridge1 - Starting a network connection between > vm://localhost#0 and tcp://null:0 has been established. > 2006-09-11 15:36:48,158 [main ] DEBUG > network.DemandForwardingBridge1 - stopping localhost bridge to null is > disposed already ? false > 2006-09-11 15:36:48,158 [main ] INFO > ransport.vm.VMTransportFactory1 - Shutting down VM connectors for broker: > localhost > 2006-09-11 15:36:48,159 [main ] INFO > ransport.vm.VMTransportFactory1 - Shutting down VM connectors for broker: > localhost > 2006-09-11 15:36:48,162 [main ] INFO > vemq.broker.TransportConnector1 - Connector vm://localhost Stopped > 2006-09-11 15:36:48,162 [main ] DEBUG > network.DemandForwardingBridge1 - localhost bridge to null stopped > 2006-09-11 15:37:11,246 [main ] WARN > ivemq.network.NetworkConnector1 - Could not start network bridge between: > vm://localhost?network=true and: tcp://komandur-2.desktop.amazon.com:61617 > due to: java.net.ConnectException: Connection refused > java.net.ConnectException: Connection refused -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://issues.apache.org/activemq/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
