ActiveMQ connection leak

Hi,

We have a problem in some of our apps. The no. of connections to activemq
keeps increasing.
<http://activemq.2283324.n4.nabble.com/file/n4681943/Capture.png> 


in the image connection name ending with 70, 114 are the leaked connections.
These connection remains until app is restarted and leaked connection keeps
growing.


We are using following versions

activemq broker: 5.6
activemq client version: 5.5.0
camel version: 2.12.2(earlier 2.7 which also had same issue)
Below are the configuration.

<bean id="jmsPooledConnectionFactory"
class="org.apache.activemq.pool.PooledConnectionFactory"
		destroy-method="stop">
		<property name="maxConnections" value="8" />
		<property name="maximumActive" value="500" />
		<property name="connectionFactory">
			<bean class="org.apache.activemq.ActiveMQConnectionFactory">
				<property name="brokerURL"
value="failover:(tcp://localhost:61616,tcp://localhost:61617)" />
				<property name="closeTimeout" value="10" />
				<property name="clientIDPrefix" value="any1"/>
			</bean>
		</property>
	</bean>

	<bean id="jmsConfig"
class="org.apache.camel.component.jms.JmsConfiguration">
		<property name="connectionFactory" ref="jmsPooledConnectionFactory" />
		<property name="asyncConsumer" value="true" />
		<property name="concurrentConsumers" value="1" />
	</bean>

	<bean id="activemq"
class="org.apache.activemq.camel.component.ActiveMQComponent">
		<property name="configuration" ref="jmsConfig" />
	</bean>


Help is much appreciated.

Usually means a client is churning through connections when they don't need
to.

Thanks for your reply. Do you have any idea why connections keep changing. My
guess is because of idletimeout 30s. But in another application with similar
config the connections doesn't change.

If you can reproduce this, send it over, attach it to a JIRA.
Otherwise, you might some additional debugging you need to do on your
side... like what rogue consumers are opening up connections and leaving
them open.
