Subject ACTIVE MQ Error :org.apache.activemq.transport.tcp.ExceededMaximumConnectionsException
Date Mon, 09 Jun 2014 08:13:06 GMT
Hi all,

Kindly explain the possible cause and solution for the following ActiveMq
error


/Connections=1000 | TransportConnector               | 126 -
org.apache.activemq.activemq-core - 5.7.0.fuse-71-047 | Could not accept
connection :
*org.apache.activemq.transport.tcp.ExceededMaximumConnectionsException:
Exceeded the maximum number of allowed client connections. See the
'maximumConnections' property on the TCP transport configuration URI in the
ActiveMQ configuration file (e.g., activemq.xml)*09 Jun 2014 01:01:26,698 |

3.0.7.RELEASE | Could not refresh JMS Connection for destination

negotiation timeout: peer did not send his wire format.



The Active MQ Bean configured to connect to the JMS system  in the route
file is as follows. 

<bean id="activemq"
class="org.apache.activemq.camel.component.ActiveMQComponent">
		<property name="brokerURL" value="tcp://localhost:61630"/>
		<property name="userName" value="admin"/>
		<property name="password" value="admin" />
	</bean>


The following is the activemq.xml config file contains

<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="properties">
            <bean class="org.fusesource.mq.fabric.ConfigurationProperties"/>
        </property>      
    </bean>

    <broker xmlns="http://activemq.apache.org/schema/core"
            brokerName="${broker-name}"
            dataDirectory="${data}"

                    <constantPendingMessageLimitStrategy limit="1000"/>
                  </pendingMessageLimitStrategy>
                </policyEntry>
                <policyEntry queue=">" producerFlowControl="true"
memoryLimit="1mb">
                </policyEntry>
              </policyEntries>
            </policyMap>
        </destinationPolicy>
 
        <managementContext>
            <managementContext createConnector="false"/>
        </managementContext>

        <persistenceAdapter>
            <kahaDB directory="${data}/kahadb"/>
        </persistenceAdapter>

                </memoryUsage>
                <storeUsage>
                    <storeUsage limit="100 gb"/>
                </storeUsage>
                <tempUsage>
                    <tempUsage limit="50 gb"/>
                </tempUsage>
            </systemUsage>
        </systemUsage>
        
        <transportConnectors>
            <transportConnector name="openwire"
uri="tcp://0.0.0.0:0?maximumConnections=1000"/>
        </transportConnectors>
    </broker>

Am I missing anything in the bean creation ?
kindly guide me with a solution for this.

Thanks,
Mahesh
