Hello, I am setting up a configuration of activemq with a network of brokers (4 brokers instances) and I am facing several problems. I am using 5.2.0 release, java 1.6.0_07
1) Sometimes, the whole set of brokers would not respond anymore for message producing. (blocking sendings). After restarting my applications, the message publishing could not restart anyway. Is it a known issue ? 2) To solve problem 1, I read the article http://activemq.apache.org/my-producer-blocks.html, and decided to set the producerFlowControl to false. With that option, I can see in the Jconsole that the Adivsory topics do not have the producer flow control set to true, even if I set the option to false in the configuration file. Can It be a problem ? I copied the configuration file of host1 broker at the end of this email. The configuration files for hosts 2, 3, 4 are similar. Can you advise on this configuration file ? I am not sure about the TTL option.
