...an update about the problem already described, it may be possible that 
I'm missing something but it may be also possible that this is useful to 
someone else. It seems now that no relation exist with using mixed 0.15 / 
0.16 libraries.

I'm using several brokers in my network, both on private internal LAN and 
(one) exposed server on DMZ port of our firewall. During my tests the most 
common setup is:

- one broker (0.15) is configured with four different bridges, all of them 
are for "#" topic and "both" directions
- the bridges are directed to three local brokers and one public broker
- the other four brokers (mix 0.15 / 0.16) have no other bridge configured
- we often switch off/on the connected brokers

Until yesterday everything was working fine, messages delivered and 
dispatched as expected, no replication or missed message.

This morning:
- if I configure the "central" broker with one bridge to one local broker, 
all messages published on one of the two brokers get duplicated
- if I configure the "central" broker with one bridge to another local 
broker, all messages published on one of the two brokers are repeated as 
an infinite loop

Of course I already tested many other combinations of bridges between the 
other brokers and everything works. It seems to me that some 
networking-related bit of configuration on this machine is messing things! 
I rebooted several times and also uninstalled and re-installed again 
mosquitto (Ubuntu based), no way... before I throw away the server and 
install it again from scratch, anything I can debug here??
