Sorry what exactly do you refer to when saying "don't have persistence set to true"? Do you refer to the persistence attribute on the broker xml element? If sets not set it defaults to true. Your memoryUsage configuration is well beyond the JVMs max heap size. So you should not run out of memory because of keeping too many messages in the brokers memory. The rest of the broker config looks ok as well. Do you by any chance have a large number of client connections to the broker? Each client connection results in two threads being created which obviously also requires a some amount of Java heap space. I suggest you monitor your broker usage closely using jconsole and check for any unusual number (i.e. jvm heap size increasing over time, the Broker MBean statistics, destination statistic, number of subscriptions). One of these should probably indicate if and where there is a problem. Regards, Torsten Mielke tors...@fusesource.com tmielke.blogspot.com
