[SR-Users] dmq issues

[Julien Chavanton]

Hi Aydar,

You can have only one notification_address in this case the last one will
be used "192.168.150.225" this will be you DMQ master node

I know the bus can break if you shutdown multiple nodes at the same time
and one of them is the master node and then you restart them. (not sure if
this is your case)

If this happens the only option I can see is to restart all nodes one by
one.

I think this case could be handled better maybe by adding a dmq resync
command that can recreate the bus .
