Problems with reconnecting broker to network of brokers after broker shutdown
-----------------------------------------------------------------------------
Key: AMQ-1301
URL: https://issues.apache.org/activemq/browse/AMQ-1301
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 4.1.2
Reporter: Pieter
When using a network of brokers, I get problems in the following scenario.
Consider two brokers, broker1 and broker2, connected to eachother (see config
below). Everything works ok: durable consumers on topics get messages sent to
either server. The messages are all persistent.
The problems occur in this scenario:
1. Bring down one of the brokers, let's say broker2 (all consumers and
producers connect to the other server, without any problems)
2. Start the killed broker2 again
3. The broker2 reconnects to the network as expected
4. However, messages don't get propagated correctly on the network anymore.
Consumers on broker1 don't get messages sent to broker2 anymore, and messages
from broker2 get sent to broker1 over and over again. This can also be seen in
the webconsole for example, where the number of messages in the queue grows
rapidly.
The only way to fix this is to kill all brokers, and remove the persistent
message stores. THis is unacceptable, since this loses messages.
Config is below:
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:util="http://www.springframework.org/schema/util";>
<broker brokerName="broker1" useJmx="true" persistent="true"
xmlns="http://activemq.org/config/1.0";>
<persistenceAdapter>
<journaledJDBC journalLogFiles="5"
dataDirectory="${activemq.base}/activemq-data"/>
</persistenceAdapter>
<transportConnectors>
<transportConnector name="openwire" uri="tcp://localhost:61616"/>
<transportConnector name="stomp" uri="stomp://localhost:61627"/>
</transportConnectors>
<networkConnectors>
<networkConnector name="ha-network"
uri="static://(tcp://localhost:61618)" networkTTL="5"/>
</networkConnectors>
</broker>
