Hello,
As a follow-up, on the network side we have turned off the firewalls on the 2 geoservers and we are still getting the error. The error message below indicates it is trying to start a network bridge with itself - communicate between its own instanceName and localhost (127.0.0.1)). Is this expected behaviour – or should it try to start a bridge with another server instance?
We have GeoServer 2.8.2 installed with Java 8 Update 92.
2016-09-21 08:10:43,834 WARN [network.DiscoveryNetworkConnector] - Could not start network bridge between: vm://3404d32d-6cd6-4ccb-a9f8-2ee428c12977?async=false&network=true and: nio://127.0.0.1:57496 due to: java.net.ConnectException: Connection refused: no further information
Is there any other suggestions we can try? Maybe a configuration tweak somewhere?

Hi Nuno,
We verified that the logs match the contents as outlined below, so we will consider the brokers are correctly enabled. We will proceed to look at the network. Thanks for your feedback.

Hi,
The ERROR line in the log is a “false error” that log should actually be a INFO.
Debugging the embedded broker is not very easy since he don’t have access
to ActiveMQ web console.
In fact you can consider the broker is correctly enable if you have something like this:
21 Sep 17:17:50 ERROR [cluster.impl] - Started the embedded brokerURI: BrokerService[f088d295-ab15-470a-a45e-bba8cc3fad8a]

Hi Andrea,
The GUI page indicates Embedded broker is enabled.
Logs appear to indicate broker is enabled. Getting messages like:
2016-09-21 08:02:56,277 ERROR [cluster.impl] - Started the embedded brokerURI: BrokerService[3404d32d-6cd6-4ccb-a9f8-2ee428c12977]

Although we are not sure why the Started the embedded line indicates ERROR (is this a true error; or false reprting)
As I think we can conclude embedded broker is enabled, looking at the network is our second troubleshooting step so we will investigate that angle.
Thanks for your feedback.

Hi Kevin,
I’m just going by memory, but believe you can simply look at the configuration page for the cluster to
check if the embedded broker is enabled? It should also be logging on the logs on startup.
However, per to peer in the default configuration requires multicast to be enabled in your network, so that nodes
can find each other. Is that the case for you?
Cheers
Andrea

Hello,
We have set up clustering between 2 geoservers. We want to implement the “Peer-to-peer newtork with embedded brokers and shared data directory” topology.
We are using the default cluster configuration (broker.xml; cluster.properties; embedded-broker.properties). However, the geoserver.log is reporting errors like:
2016-09-21 08:10:43,834 WARN [network.DiscoveryNetworkConnector] - Could not start network bridge between: vm://3404d32d-6cd6-4ccb-a9f8-2ee428c12977?async=false&network=true and: nio://127.0.0.1:57496 due to: java.net.ConnectException: Connection refused: no further information
As a first troubleshooting step, we want to verify embedded broker is running on each server. Is there a way to verify the embedded broker is running?
Thanks,
Kevin
