multiple network connections FuseMQ

[redalert....@gmail.com]

Hi,

I'm testing out FuseMQ.
I have successfully set up a root container with 4 children (2 pairs).
Then these all have the MQ component installed like this:
fabric:mq-create --group first --networks second --assign-container first1,first2 first
fabric:mq-create --group second --networks first --assign-container second1,second2 second

Some additional profile-edit has been done to set user/password

This all works fine, but now setup a new container on a second machine, joined it with fabric:join, added another 2 child containers with a master/slave broker and attempt to network them with the existing 2.
Now it appears that only the first network connection is made (property "network=first,second" in the file "org.fusesource.mq.fabric.server-third-broker.properties", and I also added the 'third' network to the existing 2 profiles)
This results in messages not being delivered to all brokers, but only the 1 with the connection. Juggling the order around in the properties will change the connection from 'first' to 'second' into from 'first' to 'third'.

2 groups: first <===> second

3 groups: first <===> second <=== third
or: first ====> third <====> second
or....
 
Does anyone have any idea on how to fix this?

Much appreciated.

Regards,
Steven
