Don't use static and multicast at the same time. If you enable static {{networkConnector}}s then disable multicast and vice versa.
When using a network of containers in <servicemix>/activemq.xml ensure that the brokerName attribute is unique for each node in the cluster. This is to ensure that the instances in the network can uniquely identify each other.
Ensure the jbi container name configured in <servicemix>/servicemix.xml is unique to the cluster.
If you are also using a HA configuration then the brokerName attribute should be the same for both the master and the slave.
When configuring a network of containers you need to to ensure that you have a unique persistent stores for each ACTIVE instance. If you are using a JDBC datasource, this means a separate database for each ACTIVE instance.
It is possible to setup a network of containers on the same host. You will need to change the JMS ports and transportConnector ports to avoid port conflicts.
Edit the <servicemix>/conf/servicemix.properties, changing the rmi.port and activemq.port as appropriate.
