We install activemq on 2 linux vm servers.
I have 1 NFS shared folder that running on diferent machine.
When we disable the network from the master server, server 2 become master and all fine, but when we enable again the network on first server.
both server 1 and server two become master ( we can enter to admin page, topic msg can be send to both)
this is critical issue since client can be connected to any one and will miss msges.
