Broker stops to accept messages
-------------------------------
Key: AMQ-3728
URL: https://issues.apache.org/jira/browse/AMQ-3728
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.5.0
Environment: Linux, 64bit, JDK 6u30 64bit
Reporter: Marek Slama
I have following configuration:
1.One producer
2.One broker on the same machine as producer.
3.One offline durable subscriber but I have enough storage size so it should
not overflow.
I run our import test and it sends about 10 messages/s. After some hours of run
I start to get:
many javax.jms.JMSException:
org.apache.activemq.transport.RequestTimedOutIOException (I set send timeout 2s
to avoid infinite block in case that broker storage is full. So first question
is why it happens when there should be enough space. I will provide my broker
configuration below.)
Then I get:
javax.jms.JMSException: Cannot send, channel has already failed:
usfr-cmsnpdev.insideidc.com/10.1.4.42:61616
javax.jms.JMSException: Cannot send, channel has already failed:
usfr-cmsnpdev.insideidc.com/10.1.4.42:61616
(ActiveMQ Connection Executor:
tcp://usfr-cmsnpdev.insideidc.com/10.1.4.42:61616) Failed to send message.:
javax.jms.JMSException: Broken pipe
some more
javax.jms.JMSException: Cannot send, channel has already failed:
usfr-cmsnpdev.insideidc.com/10.1.4.42:61616
and then all the time:
javax.jms.IllegalStateException: The Session is closed
I have simple producer code. It is Spring bean. I create connection and session
when bean is created. For every send message I create producer and close it:
{code}
//Init code
connection = connectionFactory.createConnection();
connection.setExceptionListener(new ExceptionListener() {
public void onException(JMSException ex) {
logger.error("Failed to send message.", ex);
}
});
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
....
//Send code
private void sendMessage(String xmlMessage, Topic topic, String
containerId) {
MessageProducer producer = null;
try {
// Create the producer.
producer = session.createProducer(topic);
TextMessage txtMessage = session.createTextMessage(xmlMessage);
producer.send(txtMessage);
} catch (JMSException ex) {
logger.error("", ex);
} finally {
try {
if (producer != null) {
producer.close();
}
} catch (JMSException ex) {
}
}
}
{code}
Use default connection factory:
{code}
<bean id="idc_metacop_jmsFactory.prototype"
class="org.apache.activemq.ActiveMQConnectionFactory"
abstract="true">
<property name="brokerURL" value="${metacop.jms.brokerURL}"/>
<property name="sendTimeout" value="2000"/>
</bean>
{code}
Log from broker:
{code}
2012-02-17 21:55:40,389 | INFO | Transport failed:
org.apache.activemq.transport.InactivityIOException: Channel was inactive for
too (>30000) long: /10.1.4.42:56166 |

<transportConnectors>

</transportConnectors>
</broker>
{code}
BTW is there any way how to purge even undelivered messages from broker
storage? Or how to monitor number of messages in storage? I tried to delete
offline durable subscribers from Web Admin but data folder size does not change
but I have no way how to see if messages was really removed from storage (and
db is not compacted only or if messages stay in storage.
