> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.2.0
> Environment: ActiveMQ 5.2. Linux Redhat 64bits. Java 1.6 - multi
> network interfaces
> Reporter: Eric
> Fix For: 5.x

> We are on a production system for an ERDF major project.
> We have about 15 servers called tpnocp"XY"v [ "XY" = 01,02,03,04,.. ]. On
> these servers, some Java processes are launched. Some of them have ActiveMQ
> embedded brokers. Generally speaking, these brokers are linked together by
> about 4 different networks of brokers with duplex or not duplex network
> connectors. Multicast discovery mechanism is used to dynamically create
> brokers connections. Default Multicast IP is used with different groups.
> I'm currently in a situation where
> - a java process is launched on tpnoc09v server, and has an embedded broker
> named "BEA-tpnocp09v"
> - this embedded broker dynamically discovered 4 brokers that are embedded in
> 4 java process that are launched on the tpnocp13v server (tpnocp13v-bus IP
> address is used), and connected in full duplex to them.
> - a fifth process is executed on the same tpnocp13v server, has an embedded
> broker which has the same ActiveMQ configuration as the 4 others that are
> connected to the "BEA-tpnocp09v" broker.
> - the "BEA-tpnocp09v" embedded broker is not connected to the fifth embedded
> broker.
> - Multicast packets relative to this fifth broker, seem to be correctly
> received by tpnocp09v server (tcpdump)
> - All seems stable.
