[jira] Created: (AMQ-1455) Network bridge keeps falling down
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}

[jira] Commented: (AMQ-1455) Network bridge keeps falling down
Posted by "David Dossot (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/activemq/browse/AMQ-1455?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_40325 ]
David Dossot commented on AMQ-1455:
-----------------------------------
The NPE is thrown on this line:
Message message = md.getMessage().copy();
By following the code before this line, md can not be null, so this is getMessage() that is null.
Is this because I am erroneously using the VM transport? The reason I am using this transport is because my brokers are embedded in Java apps that connect to the local broker using the VM adapter.

[jira] Commented: (AMQ-1455) Network bridge keeps falling down
Posted by "David Dossot (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/activemq/browse/AMQ-1455?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_40336 ]
David Dossot commented on AMQ-1455:
-----------------------------------
I have stopped using VM transport altogether from my embedded client application, but the problem still happens: the bridge keeps falling down.
I noticed the issue seems to happen if I have a queue browser (from Hermes) on the same distributed queue my application is using.
I recognize the issue is hard to reproduce on your side, but in the mean time can the bridge be made more resilient to runtime exceptions so it recovers and does not stop?

> 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:
