------------------------------------
This same exact thing happens for me as well. I am also using embedded brokers with VM transport
> Network bridge keeps falling down

>
> Key: AMQ-1455
> URL: https://issues.apache.org/activemq/browse/AMQ-1455
> Project: ActiveMQ
> Issue Type: Bug
> Components: Transport
> Affects Versions: 5.0.0
> Environment: apache-activemq-5.0-20071008.215641-19, RHEL 4, JDK 1.6.0_02
> Reporter: David Dossot

> The bridge between two nodes keeps falling down after a few minutes of use.
> This is maybe a misconfiguration and totally my bad, so here is the network config:
> <transportConnectors>
> <transportConnector uri="vm://${esb.node.name}" />
> <transportConnector uri="tcp://localhost:58080" discoveryUri="rendezvous://dev-esb-node" />
> </transportConnectors>
> <networkConnectors>
> <networkConnector conduitSubscriptions="true" decreaseNetworkConsumerPriority="true" dynamicOnly="true"
> networkTTL="64" uri="rendezvous://dev-esb-node" userName="broker" password="XXX" />
> </networkConnectors>
> ${esb.node.name} resolves to "backbone-node-8080" on one box and "collection-node-8080" on the other.
> And here are the errors when the bridge crashes:
> 11:04:46,241 DEBUG [org.apache.activemq.network.DemandForwardingBridge] backbone-node-8080 Forwarding sub on vm://backbone-node-8080#4 from collection-node-8080 : ConsumerInfo {commandId = 4, responseRequired = true, consumerId = ID:ddo-mbp.local-51198-1191953085196-0:0:1:1, destination = queue://esb.admin.errors, prefetchSize = 500, maximumPendingMessageLimit = 0, browser = true, dispatchAsync = false, selector = null, subscriptionName = null, noLocal = false, exclusive = false, retroactive = false, priority = 0, brokerPath = null, optimizedAcknowledge = false, noRangeAcks = false, additionalPredicate = null}
