------------------------------------------------------------
I create new producer for every message send. I use
org.apache.activemq.ActiveMQConnectionFactory as connection factory. Code
sample for sending message is as follows:
{code}
private void sendMessage(String xmlMessage, Topic topic, String
containerId) {
String topicName = null;
MessageProducer producer = null;
try {
topicName = topic.getTopicName();
// Create the producer.
producer = session.createProducer(topic);
TextMessage txtMessage = session.createTextMessage(xmlMessage);
producer.send(txtMessage);
} catch (JMSException ex) {
//Exception handling....
} finally {
//Closing producer ...
}
}
{code}
Connection and session is created in init method. So it does not use any
connection pooling.

> 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.

> not overflow.
> I run our import test and it sends about 10 messages/s. After some hours of

> {code}javax.jms.JMSException:
> org.apache.activemq.transport.RequestTimedOutIOException{code}
> (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:
