Hi, i am starting a broker via spring config and i would like to enable the LoggingBrokerPlugin it in. I am doing this via: ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("activemq-spring.xml"); XBeanBrokerService broker = (XBeanBrokerService)app.getBean("broker

Re: Crashing an AMQ producer in ~12 seconds

Hi Phill, from what i can see, you are sending persistant messages to a topic, this means that if no one is listening on that topic, your messages will he stored (aka held in memory) until someone listens on that topic. this would explain why you run out of memory. Essentially you experiencing th

Broker MemoryPercentUsed 100% with no queues

Hi, sometimes our activeMQ freezes with the JMX console reporting that the Borker's MemoryPercentUsed is 100%. In out activeMQ setup, we have no queues and _only_ topics. We have this to avoid the memory issues related with slow-consumers. we are running activeMQ 4.1.1. What is also strange is

ActiveMQ Tries to resolve ip adresses to names which failes when only a proxy should do that

Hi, We have been having cases recently were people cannnot connect to our ActiveMQ (4.1) when using proxies. After lots of digging, i have found that the issue may be in this class: org.apache.activemq.transport.tcp.TcpTransport and especially in the connect() method. There we call remoteAddress.

Jms Destination lifetime question

Hi, ActiveMQ makes it very easy to create JMS Destinations, but seems like they are not every easy to destroy. does this mean that i will case ActiveMQ to crash if i create too many JMS Destinations? Also if a destination is created, and unused, is it cleaned up or destroyed? Regards, Saqib -
