Hi, I am using embedded Activemq broker (5.3 Version), Flex client and STOMP protocol for the communication.
The problem is, When unexpected error occurs in the Flex client, Activemq broker memory usage increases gradually and then it hangs giving the following message in the log file Memory usage change from: 1% of available memory, to: 2% of available memory . . . Memory usage change from: 99% of available memory, to: 100% of available memory Usage Manager memory limit reached for topic://a. Producers will be throttled to the rate at which messages are removed from this destination to prevent flooding it. See http://activemq.apache.org/producer-flow-control.html for more info Below is the xml configuration we use <beans xmlns="http://www.springframework.org/schema/beans"; xmlns:amq="http://activemq.apache.org/schema/core"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd";> <!-- The <broker> element is used to configure the ActiveMQ broker. --> <broker xmlns="http://activemq.apache.org/schema/core"; persistent="false" useJmx="true" brokerName="PRI" > <transportConnectors> <transportConnector name="Stomp" uri="stomp://0.0.0.0:8084"/> <transportConnector name="Nio" uri="nio://0.0.0.0:8086"/> <transportConnector name="Tcp" uri="tcp://0.0.0.0:8087"/> </transportConnectors> </broker> </beans> We use NON-PERSISTENT messages and send to topic. The client listens to the topic and process the message. The jconsole shows the broker MemoryPercentUsage as 100% when activemq hangs. Why does an error in client crashes the Activemq server??? Do anyone face the same issue?? Only restarting the broker helps. I haved changed a lot of modification in the xml configuration but could not find the root cause. Kindly help me on this as this is a production issue. -- View this message in context: http://old.nabble.com/Activemq-broker-hangs-when-stomp-client-disconnects-unexpectedly-tp26283384p26283384.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
