> I've discovered a reproducible memory leak. After discussion on IRC, it is
> believed to be related to my network of brokers configuration.
> I have a total of 4 brokers configured on 4 hosts (activemq1,2,3,4).
> activemq1 and activemq2 are a shared filesystem master slave pair. activemq3
> and activemq4 are setup in a similar way as a master/slave pair.
> Only one of activemq1 and 2 will be active at a time, likewise only one of
> activemq3 and 4.
> Both activemq1 and activemq2 have a config with the following
> networkConnector.
> <networkConnectors>
> <networkConnector
>
> uri="static://(tcp://activemq3:61616,tcp://activemq4:61616)"
> name="Connection to 3 and 4"
> networkTTL="5"
> dynamicOnly="true"/>
> </networkConnectors>
> The broker will only be able to connect to either 3 or 4 as only one can be
> running at a time.
> For obvious reasons, connecting to the slave will fail, but the connection
> attempt will be retried every 30 seconds by default (more often on initial
> startup due to backoff algorithm).
> It is believed that the continuous reconnect attempts are the source of the
> memory leak.
